+84 To measure a stone face carved on the side of a mountain, two sightings
750 feet from the base of the mountain are taken. If the angle of elevation to the bottom of the face is 31° and the angle of elevation to the top is
34°, what is the height of the stone face?
The height of the stone face is ___ feet?
+37146 Remember tangent of right triangle = opposite side/adjacent side ?
Tan 34 = top / 750 750 tan 34 = top similarly for the bottom....subtract the two
750 tan34 - 750 tan 31 = height
