Tammy is an electrician. When using a ladder, her company requires the angle formed between the ground and the ladder to be within 3° of 75° so that she remains safe. If she is using a 20-foot ladder and places the ladder 5 feet from the wall, is this within safety protocol? What is the approximate angle formed between the ground and the ladder?(1 point)

Yes, the angle formed is approximately 76°.

No, the angle formed is approximately 90°.

Yes, the angle formed is approximately 73°.

Compute θ = arccos(adjacent/hypotenuse) = arccos(5/20) = arccos(0.25) ≈ 75.5°, about 76°. That is within 3° of 75°, so Yes — the angle is approximately 76°.
