A surveyor measures the angle of elevation to a point on a mountain to be 15
•. The point on the mountain is horizontally 6 miles away from the surveyor.
The vertical change in elevation from the point where the surveyor is standing
to the point on the mountain is m iles. (Round your answer to the
nearest hundredth of a mile.)

Step-by-step explanation:

sorry dont know just need points

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
