make sure your calculator is in Degree mode.

Answer 2

Answer:

Angle x = 60.1 degrees

Step-by-step explanation:

Given : height of the ladder is 15 ft that is the hypotenuse

The top of the ladder is  13ft off the ground.

That is the oppposite side of angle x

Since this forms a right angle triangle we use trigonometric ratios to find x

We know the opposite side and the hypotenuse

sin(x) = opposite / hypotenuse

$sin(x) = \frac{13}{15}$

$x = sin^{-1}(\frac{13}{15})$

x= 60.073565

Angle x = 60.1 degrees
