Answer:
The angle of elevation is 36.87°
Step-by-step explanation:
We use the sine ratio to determine the angle of elevation, x.
The sine ratio is given as:
[tex] \sin(x) = \frac{opposite}{hypotenuse} [/tex]
We substitute the opposite side, which is the height of the pole and the hypotenuse, which is the height of the ladder to get:
[tex] \sin(x) = \frac{18}{30} [/tex]This implies that;
[tex] \sin(x) = 0.6[/tex]
[tex]x = \sin^{ - 1} (0.6)[/tex]
[tex]x = 36.87 \degree[/tex]
