Answer:
theta = 44.4 degrees
Step-by-step explanation:
Since this is a right triangle, we can use trig formulas
cos theta = opposite/ hypotenuse
cos theta = 15/21
Take the inverse of each side
cos^ -1 (cos theta) = cos ^-1 (15/21)
theta =44.4153086
theta = 44.4 degrees

What is the length of its side?
Answers
Answer:
the length of cube
is 2 mm
Answer:
2m
Step-by-step explanation:
A cube is a 3-dimensional object with all sides of equal length. So, length = breadth = height
Let the side of cube be x.
Then Volume of cube = x * x * x
So, length (side) of cube is 2m
What is the scale factor from ABC to DEF?
Answers
Within similar triangles, the angles are the same. So, we need to look at the side lengths then.
72 to 12
66 to 11
42 to 7
In each pair of corresponding side lengths, the original side length from triangle ABC is divided by 6 (or multiplied by 1/6) to get the smaller side length on triangle DEF.
The scale factor from ABC to DEF is 1/6.

Step 1: W = 7 - L
Step 2: Widths = 4, 3, 2, 1
Step-by-step explanation:
step1:
14 = 2L + 2W
14 - 2L = 2W
W = 7 - L
step2:
W = 7 - L
W = 7 - 3 = 4
W = 7 - 4 = 3
W = 7 - 5 = 2
W = 7 - 6 = 1
A man is 40 years old and his son is 5years old. In how many years will the father be 3 times the age of his son.
Answers
12 1/2 years
Step-by-step explanation:
Let the unknown be n. Then 40+n = 3(5+n).
Performing the multiplication:
40+n = 15+3n
Isolate n and combine the constant terms:
25=2n, so n= 25/2 years

A triangle has vertices on a coordinate grid at D(6,-1)D(6,−1), E(-4,-1)E(−4,−1), and F(-4,-6).F(−4,−6). What is the length, in units, of DE ?
Answers
Answer:
2units
Step-by-step explanation:
Given the coordinates D(6,−1), E(-4,-1), using the distance formula
DE = √(x2-x1)²+(y2-y1)²
DE = √(-1-(-1))²+(4-6)²
DE = √(-1+1)²+(-2)²
DE = √0+4
DE = √4
DE = 2units
Hence the length od DE in units is 2units

Answer:
(B) Luis's, because he flipped the inequality sign when he subtracted
Step-by-step explanation:
Let's evaluate each answer choice:
"Amelia's, because the variable term must be isolated on the left side"
This answer choice is wrong! Whichever side the variable term is isolated on DOESN'T affect the answer of the problem.
"Luis's, because he flipped the inequality sign when he subtracted"
This answer choice is right! Only flip the inequality sign when dividing a NEGATIVE number.
"Shauna's, because she did not apply the subtraction property of equality properly"
This answer choice is wrong! Shauna correctly applied the subtraction proper by subtracting 6.5 from both sides.
"Clarence's, because the terms he added together were not like terms"
This answer choice is wrong! Clarence added 8.1 to both sides, so he added 8.1 to 6.5, which are like terms.

The distance from A to C can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
3² + 4²
= 16 + 9
