Ask in the photo. Thanks

C

Step-by-step explanation:

We are given the base which is the horizontal side of the triangle. Remember that for later

We are also given an angle that is made between the ground and top of the flagpole. That angle is adjacent to the base

We are asked to find the vertical side or height of the flagpole.

Since we are given a side that is adjacent to the angle and a side that is opposite of that angle we will use

TANGENT.

plug in the numbers

Multiply 10 by both sides

So the answer is C
