Answer to Problem 21PPS
The angle of elevation and depression are
Explanation of Solution
Given information:
Length from base to peak:
Calculation:
J is taller than the target. Thus, J throws the dart at an angle of depression.
The side opposite the angle of depression is
Consider,
The angle of depression:
As per Alternate Interior Angles Theorem the angle of depression and the angle of elevation are congruent.
Let’s draw a figure to represent the given information:
If is a
leg opposite
The angle of depression is calculated as:
K is shorter than the target. Thus, K throws the dart at an angle of elevation.
The side opposite the angle of depression is
Consider,
The angle of elevation:
Let’s draw a figure to represent the given information:
The angle of elevation is calculated as:
