A 30 foot ladder needs to reach 18 feet high against a building. What would the approximate angle of elevation be from the ground?

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:

We substitute the opposite side, which is the height of the pole and the hypotenuse, which is the height of the ladder to get:

This implies that;

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
