Question

At a point 15 metres away from the base of a 15 metres high house, the angle of elevation of the top is????

Answer 1

Answer:

Let angle of elevation be X.

tan(X) = 15 m /15 m

= > tan(X) = 1

= > X = 45 degrees.

Angle of elevation is 45 degrees.

Answer 2

Answer:

${45}^{o}$

Explanation:

$\tan(Θ) = \frac{15}{15} = 1 \\ therefore \: \: Θ = 1 = \tan( {45}^{o} )$
