The law of sines tells you ...
AB/sin(C) = AC/sin(B)
AB = sin(C)/sin(B)×AC . . . . . . multiply by sin(C)
AB = sin(53°)/sin(44°)×7 ≈ 8.048
The length of AB is about 8.0 units.

In right triangle EAD with right angle at A, AE=4 units, AB=BC=CD and the area of triangle ABE=6 sq units. What is the length of segment CE? Express your answer as a decimal to the nearest tenth.
Answer:
CE = 7.2
Step-by-step explanation:
Area = 1/2bh
6 = 1/2 (b)(4)
6 = 2b
3 = b b represent AB, so BC and CD is 3 unit also
Length of CE , you have a right triangle with a leg(AE) = 4 and and the other leg (AC) = 6 and the hypotenuse (CE) = x
The figure is a right triangle so you know that a² + b² = c²
4² + 6² = x²
16 + 36 = x²
52 = x²
[tex]\sqrt{52 }[/tex] = x
7.211 ≈ 7.2 = CE
Find the variance of [6 ,7 ,10 ,11 ,12 ,13 ,16 ,18 ,25].
Round off your final answer into two decimal places. (5pts)
The variance of [6 ,7 ,10 ,11 ,12 ,13 ,16 ,18 ,25] is 34.61
The sample size (n) = 9
The mean of the distribution (x_i) is the sum of the distribution divided by the number of items in the distribution.
[tex]\mathbf{x_i=\dfrac{6+7+10+11+12+13+16+18+25}{9}}[/tex]
[tex]\mathbf{x_i=\dfrac{118}{9}}[/tex]
[tex]\mathbf{x_i=13.11}[/tex]
The variance is the average between the difference of the mean, followed by squaring the result.
[tex]\mathbf{S^2 = \dfrac{\sum (x_i - \bar x)^2}{n-1}}[/tex]
[tex]\mathbf{S^2 = \dfrac{ ((6 -13.11)^2+ (7-13.11)^2+...+(16-13.11)^2+(18-13.11)^2+(25-13.11)^2}{8}}[/tex]
[tex]\mathbf{S^2 = \dfrac{276.8889}{8}}[/tex]
[tex]\mathbf{S^2 = \ 34.61}[/tex]
Therefore, the variance of the sample given is 34.61

2x+3=x+15
Help ASAP!
Answer:
x=12
Step by step explanation:
Let's solve your equation step-by-step.
2x+3=x+15
Step 1: Subtract x from both sides.
2x+3−x=x+15−x
x+3=15
Step 2: Subtract 3 from both sides.
x+3−3=15−3
x=12
Therefore,the answer is=>x=12

Sum of the Angles of a Triangle
If the three angles of a triangle
are equal, what is the
measurement of each angle?
B
C
[?] degrees
9514 1404 393
Answer:
60°
Step-by-step explanation:
If the measure of the angle is represented by A, then the sum of the three angles in the triangle is ...
A +A +A = 180°
3A = 180° . . . . . . . simplify
A = 180°/3 = 60° . . . . . divide by the coefficient of A
The three angles in an equi-angular triangle are all 60°.
__
Additional comment
If the angles are equal, so are the opposite sides. The three sides in an equi-angular triangle are also equal. Generally, such a triangle is called an equilateral triangle. It is useful to remember the angles in an equilateral triangle are all 60°.
One interesting consequence of this is that the smallest angle in any triangle can never be larger than 60°.

Scrooge invests $500. He found a bank that would pay him 4% interest, compounded monthly.
a) Type of exponential function.
b) Write a function to represent the situation.
c) If he deposits the whole $500 and does not deposit or withdraw any other amount, how much money would he have after 4 years?
The formula that can be used to determine the amount Scrooge would have in 4 years is: A(1 +r)^nm
A = Amount invested = $400
r = interest rate = 4/12 = 0,0333
n = number of years
m = number of compounding
$500(1.0333)^(12 x 4) = $586.60.
