PLEASE HURR The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h.

A=12h(a+b)

Solve for h.

h=A2(a+b)

h=2(a+b)A

h=a+b2A

h=2Aa+b

20 points! asap! a is known to be 6,500 feet above sea level; ab = 600 feet. the angle at a looking up at p is 20°. the angle at b looking up at p is 35°. how far above sea level is the peak p? find the height of the mountain peak to the nearest foot. height above sea level =
