The measure of ∠A is 29.
What is an angle?
An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.
Given that,
m∠A = (2x−13)° and m∠B = (2x+ 7)° and ∠A and ∠B are complementary angles.
Therefore
m∠A + m∠B = 90°
(2x−13)° + (2x+ 7)° = 90°
4x + 6 =90
Subtract 6 from both sides:
4x = 84
Divide both sides by 4:
x = 21

an item is regularly priced at . it is on sale for off the regular price. how much (in dollars) is discounted from the regular price?
An item is regularly priced at, 1.98$ is discounted from the regular price.
A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction. All of something is 100 percent, half of it is fifty percent, none of something is zero percent. To determine a percentage, you divide the portion of the whole by the whole itself and multiply by 100.
Given that,
First, change the percentage into decimal:
Let us assume,
Sale of regular price = 1%
1% = 1/100 = 0.01
Assume, item regular price is = 2$
Multiply 2 with 0.01:
2 * 0.01 = 0.02
Note that this number 0.02 (0.01 of 2) is the amount off from the original price (2). Subtract 2 from 0.02
2 - 0.02 = 1.98
Therefore,
An item is regularly priced at, 1.98$ is discounted from the regular price.

Given f(x) = x² - 1 and g(x) = x + 5, find h(x) = (f. g)(x).
The function h(x) = (f.g)(x) would be x² + 10x + 24.
What are composite functions?
A composite function is generally a function that is written inside another function. The composition of a function is done by substituting one function into another function. For example, f [g (x)] is the composite function of f (x) and g (x). The composite function f [g (x)] is read as “f of g of x”.
To find h(x) = (f.g)(x), we need to find the composition of the functions f(x) and g(x).
The composition of two functions f(x) and g(x) is denoted by (f.g)(x) and is defined as (f.g)(x) = f(g(x)).
In this case, we have:
h(x) = (f.g)(x) = f(g(x)) = f(x + 5)
Substituting x + 5 for g(x) in the equation for f(x), we get:
h(x) = (f.g)(x) = f(x + 5) = (x + 5)² - 1
Simplifying this expression, we get:
h(x) = (f.g)(x) = x² + 10x + 24
Hence, the function h(x) = (f.g)(x) would be x² + 10x + 24.

If A=45° B = 30°, prove that
Sin (A-B) = sinAcos B - Cos Asin B
To prove that Sin (A-B) = sinAcos B - Cos Asin B, we can use the angle subtraction formula for sine:
Sin (A-B) = Sin A Cos B - Cos A Sin B
This formula is derived from the identity:
Sin (A-B) = Sin A Cos B - Cos A Sin B
which can be derived by using the double angle identities for sine and cosine:
Sin (2A) = 2 Sin A Cos A
Cos (2A) = Cos^2 A - Sin^2 A = 2 Cos^2 A - 1 = 1 - 2 Sin^2 A
Substituting these identities into the identity above, we get:
Sin (A-B) = Sin A Cos B - Cos A Sin B
What is an angle subtraction?Angle subtraction formulas is otherwise known as angle subtraction identities. This angle subtraction formulas permit us to find the exact values of less common trigonometric angles by expressing the less common angle as the difference of two common angles.

Part B: Use a complete sentence to explain how you were able to determine which values make the equation false. (4 points)
A) The integers that make the equation false are {2, 54, 86}
B) We found that by solving the linear equation.
Which integer makes the equation false?
Here we have the following linear equation:
7m - 11 = 5m + 43
And the set of the possible solutions is S: {2, 27, 54, 86}
The simplest way to see which integer makes the equation false, we just need to replace the values of the possible solution sets and see which ones give a false equation.
Another method is to simplify the equation, and i will do that:
7m - 11 = 5m + 43
7m - 5m = 43 + 11
2m = 54
m = 54/2
m = 27
So the equation has a single solution, m = 27.
Then the integers that make the equation false are {2, 54, 86}

The evaluation of the segment formed by the parallel lines using Thales Theorem also known as the triangle proportionality theorem are;
8. [tex]\overline {ST}[/tex] is parallel to [tex]\overline{PR}[/tex]
9. [tex]\overline{ST}[/tex] is parallel to [tex]\overline{PR}[/tex]
10. [tex]\overline{ST}[/tex] is not parallel to [tex]\overline{PR}[/tex]
11. x = 57.6
12. x = 25.8
13. x = 11
14. x = 10
15. x = 5
16. x = 17
What is Thales theorem?Thales Theorem also known as the triangle proportionality theorem states that a parallel line to a side of a triangle that intersects the other two sides of the triangle, divides the two sides in the same proportion.
8. The ratio of the sides the segment [tex]\overline{ST}[/tex] divides the sides QR and QP of the triangle ΔPQR into are; 7/11.2 = 10/16 = 0.625
Therefore; according to the Thales theorem, [tex]\overline{ST}[/tex] ║ [tex]\overline{PR}[/tex]
9. The ratio of the sides the parallel side to the base divides the other two sides are;
33/41.8 = 15/19
45/(102 - 45) = 45/57 = 15/19
Therefore, [tex]\overline{ST}[/tex] and [tex]\overline{PR}[/tex] bisects [tex]\overline{QP}[/tex] and [tex]\overline{QR}[/tex] into equal proportions and therefore, [tex]\overline{ST}[/tex] ║ [tex]\overline{PR}[/tex]
10. The ratio of the sides the segment [tex]\overline{ST}[/tex] bisects the other two sides are;
24/57 and 19/38
24/57 ≠ 19/38, therefore [tex]\overline{ST}[/tex] ∦ [tex]\overline{PR}[/tex]
Second part; To solve for x
11. x/30 = 48/25
x = (48/25) × 30 = 57.6
x = 57.6
12. x/34.4 = (49 - 28)/28
x = 34.4 × (49 - 28)/28 = 25.8
x = 25.8
13. (2·x + 6)/52.5 = 32/60
(2·x + 6) = 52.5 × (32/60)
x = (52.5 × (32/60)) - 6)/2 = 11
x = 11
14. (x - 3)/21 = (x - 1)/27
27·x - 27 × 3 = 21·x - 21
27·x - 81 = 21·x - 21
6·x = 60
x = 60 ÷ 6 = 10
x = 10
15. (35 - 20)/20 = (4·x - 2)/(7·x - 11)
15/20 = (4·x - 2)/(7·x - 11)
15 × (7·x - 11) = 20 × (4·x - 2)
105·x - 165 = 80·x - 40
105·x - 80·x = 165 - 40 = 125
25·x = 125
x = 125/25 = 5
x = 5
16. (x - 3)/35 = 4/(x - 7)
(x - 3) × (x - 7) = 35 × 4 = 140
x² - 10·x + 21 = 140
x² - 10·x - 119 = 0
(x - 17) × (x + 7) = 0
x = 17 or x = -7
Therefore, the possible value of x is 17
x = 17
