Answer:
The angle of elevation is 32 degrees.
Step-by-step explanation:
To solve this problem, we first must recognize that the angle of elevation is the angle from the horizontal up to the plane; in other words, from Point C to Point A (where the ? symbol is located). Using this knowledge, we see that there are two other angles inside the same triangle, one measuring 90 degrees (represented by the square) and one measuring 58 degrees.
We must remember that in a triangle, the interior angles must add up to 180 degrees, so we can construct the following equation.
90+58+x = 180, where x is the unknown value
If we simplify the left side, we get
148 + x = 180
Next, we should subtract 148 from both sides to isolate the variable x.
x = 32
Therefore, the angle of elevation is 32 degrees.
Hope this helps!
