ohn wants to measure the height of a tree. He sights the top of the tree, using a mirror that is lying flat on the ground. The mirror is 36ft from the tree, and John is standing 7.7ft from the mirror, as shown in the figure. His eyes are 5ft above the ground. How tall is the tree? Round your answer to the nearest foot.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
