Question

A slide should be built in a park that has to be set up at 10 meters height and also 10 meters away from the support. What should be the angle of elevation?

(a) 45°

(b) 30°

(c) 60°

(d) 90°

This question was posed to me in a job interview.

My enquiry is from Trigonometry Application topic in portion Trigonometry Application of Mathematics – Class 10

Answer 1

The correct choice is (a) 45°

Explanation: The angle between AC and BC is the angle of elevation that has to be found.

tan⁡ θ = \(\frac {AB}{BC} = \frac {10}{10} \)

Tan θ = 1

θ = 45°
