Question

find the angle of elevation from point c to point a. angle of elevation = ?°

Explanation:

Step1: Use the property of right - angled triangle angles

In a right - angled triangle \(ABC\) (\(\angle B = 90^{\circ}\)), the sum of the two non - right angles is \(90^{\circ}\). Let the angle of elevation from \(C\) to \(A\) be \(\theta\).
We know that one of the non - right angles (\(\angle BAC\)) is \(66^{\circ}\), and \(\theta+\angle BAC = 90^{\circ}\)

Step2: Solve for \(\theta\)

\(\theta=90^{\circ}- 66^{\circ}\)

Answer:

\(24\)
