Question

Jessica sets up a volleyball net in her backyard. To secure the net in place, she extends a rope from the top of each of the two poles at a diagonal to the ground. Once the poles are placed in the ground, they are 7 feet tall; the rope she uses is 9 feet long. Using the inverse of sine, what is the approximate angle formed between the ground and the rope?(1 point)

51°

39°

45°

90°

Answer 1

Opposite side = 7 (pole), hypotenuse = 9 (rope), so θ = sin⁻¹(7/9) ≈ sin⁻¹(0.7778) ≈ 51°. Answer: 51°.
