Answer:
C. 76.81
Step-by-step explanation:
We must use one of the trigonometric ratios to find the length, L, of the ramp. If we use 16 as the reference angle, the 22 in would be our opposite side and the ramp length is the adjacent.
Therefore, we must use tan, which is :
Answer:
Step-by-step explanation:
Notice that .
The diagram already marks , so we just need to find
.
and
are vertical angles, which means they are equal in measure.
Therefore,
Since there are on each side of a line, we have the following equation:
.
Plugging in , we have:
.
Therefore,
.
