A 15-foot ladder is resting against a wall and makes an angle of 48 degree's with the ground. Find the height to which the ladder will reach on the wall

Answer 1

The diagram is a right triangle, so the length of the ladder would be its hypotenuse, and the height of the wall, the opposite side of the angle of 48. Then

Sen 48= x / 15

Clear x and that's the answer.
