Question: 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)  

Responses:  

Yes, the angle formed is approximately 76°.  

No, the angle formed is approximately 14°.

No, the angle formed is approximately 90°.

Yes, the angle formed is approximately 73°.

Compute θ with cos θ = adjacent/hypotenuse = 5/20 = 0.25, so θ = arccos(0.25) ≈ 75.5° ≈ 76°.
Allowed range is 75° ± 3° = 72°–78°, so yes — this is within safety protocol.
