Atree casts a shadow of 23 meters. at the end of the shadow, the angle of elevation to the top of the tree is 37 degrees. find the height of the tree

The best answer would give the hight of the shadow without the angle of elevation, not knowing the time of the day the shadow was measured

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
