A tunnel for a new highway is to be cut through a mountain that is h= 385 feet high. At point A, which is a distance of 150 feet from the base of the mountain, the angle of elevation is 40 ^∘
. On the other side of the mountain at point B, which is a distance of 180 feet from the base of the mountain, the angle of elevation is 35 ^∘
. Compute x, which is the length of the tunnel. To present an angle in degrees, type deg or use the CalcPad degree symbol. For example, sin(30deg).
