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?

Cosine theta = adjacent/hypotenuse = 5/20 = 0.25, so theta = arccos(0.25) ≈ 75.5° ≈ 76°. This is within 3° of 75°, so Yes — the angle is approximately 76°.
