<u>Given</u>
<u>Solve for x</u>
- 2x = 7 - 3
- 2x = 4
- x = 4/2
- x = 2
Answer:
m<F = 95°
Step-by-step explanation:
We'll begin by calculating the value of x. This can be obtained as follow:
m<C = 50
m<A = (10x – 5)
m<B = m<G = (2x + 15)
m<C + m<A + m<B = 180 (Sum of angles in a triangle)
50 + (10x – 5) + (2x + 15) = 180
50 + 10x – 5 + 2x + 15 = 180
50 – 5 + 15 + 10x + 2x = 180
60 + 12x = 180
Collect like terms
12x = 180 – 60
12x = 120
Divide both side by 12
x = 120 / 12
x = 10
Finally, we shall determine the value of m<F. This can be obtained as follow:
m<F = m<A
But
m<A = 10x – 5
x = 10
Therefore,
m<F = 10x – 5
m<F = 10(10) – 5
m<F = 100 – 5
m<F = 95°

Get the required answer
The number of students that got B or a better grade on the test = 19 students rounded to a whole number.
A = old value = 3431
B = new value = 3732
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (3732-3431)/3431 ] * 100%
C = (301/3431) * 100%
C = 0.0877 * 100%
C = 8.77%
<h3>Answer: Roughly an 8.77% increase</h3>
Note: if C was a negative value, then we'd have a percentage decrease
