Question

finding the measure of an angle of elevation
what is the measure of the angle of elevation from point l to point j?
37°
45°
53°
137°

Explanation:

Step1: Identify right triangle angles

$\triangle LJK$ is right-angled at $K$, so $\angle L + \angle J = 90^\circ$.

Step2: Calculate angle at L

The given angle at J (alternate angle) is $53^\circ$. Solve for $\angle L$:
$\angle L = 90^\circ - 53^\circ$

Answer:

37°
