Answer:
x ≈ 34.9
Step-by-step explanation:
Using the sine ratio in the right triangle
sin35° =
= 
Multiply both sides by x
x × sin35° = 20 ( divide both sides by sin35° )
x=
≈ 34.9 ( to the nearest tenth )
The terms appear to increase by a multiple of -2. The first 7 terms are:
-4 + 8 + -16 + 32 + -64 + 128 + -256. Add these together.
The sum of these numbers is -172.
