Can someone help me with this is too hard for me. If the angle at the top of the tower is known, a surveyor would use the . function9 to find the length x.

The cosine of a 50° angle is a1 this represents the value created when length is divided by feet.

If the angle near the top of the tower was changed to 60°, the cosine would be 0.5; now the length of x would be feet.

If the angle near the top of the tower was changed to 60°, the angle from the light and the ground would be degrees.
