You are driving toward a tower. At your first stop, the angle of elevation to the top of the tower is 28 degrees. Then you drive 550 ft. toward the tower and stop again. Now the angle of elevation is 40 degrees. To the nearest foot, what is the height of the tower? Please answer!! I've been stuck on this for an hour

therefore,

by the low of sine,

which is the required equation for finding the value of x,
