You are tackling a trigonometry question here. I recommend remembering the functions and drawing the triangle out.
Answer:
x = 3
Step-by-step explanation:
set up proportion based on corresponding sides of similar triangles:
15 / 10 = 15 + x / 12
cross-multiply:
10(15 + x) = 15(12)
150 + 10x = 180
10x = 30
x = 3
First, you’re starting equation should look something like this:
19.99+2h= 14.99+2.50h
H equaling hours
You would then subtract 2h from 2.50h, so now you’re equation will look like this:
19.99=14.99+0.50h
Then, subtract 14.99 from 19.99. The equation should look like:
5=0.50h
Finally, divided 0.50h to 5 to get 10
10=h
You’re finally answer should be, It would take 10 hours for the Internet cost to be equal. The monthly charge would then be 39.99. You can find your answer by replacing h on either sides or your starting equation and insert 10.

Answer:
a) 77.13
b) 179.97
Step-by-step explanation:
3x + 3x + 4x + 5x + 6x + 7x = (6 - 2) × 180
28x = 720
x = 720/28
x ≅ 25.71
3 × 25.71 = 77.13 = smallest angle
7 × 25.71 = 179.97 = largest angle
