(t) Rnd the solutions ishring over a straight highwas. determines the angles of

As figure is not clear, so I consider distance between A and B = 8 mi

Angle x = 32 degree

Angle y = 48 degree

Let the distance of the plane from point A = b

And the elevation of the plane = h

Now sin100/8 = sin48/b

b = 6.04 miles

And sin32 = h/6.04 =========> h = 3.2 miles
