In exercises 21 to 30. Use the drawings. Where provided, to solve each problem. Angle measures should be found to the nearest degree; lengths should be found to the nearest tenth of a unit.
A 4-m beam is used to brace a wall. If the bottom of the beam is 3 m from the base of the wall, what is the angle of elevation to the top of the wall?
what is the angle of elevation to the top of the wall.
Procedure used:
In any right triangle ABC with
Calculation:
Given:
Length of the beam
Distance of the wall from the foot of the beam
Let us structure the given figure as follows as a right triangle.
In the above triangle we have
