The angle of elevation of the sun from the ground to the top of a tree is 36°.

We are given that:

The sun from the ground to the top of a tree when a tree that is 10 yards tall casts a shadow 14 yards long.

Now by using the trigonometric identity .

tan θ = P / B

As figure is  given below .

AB =  Perpendicular = 10 yards

BC =  Base = 14 yards

Putting all the values in the trigonometric identity .

tan θ = 10 / 14

θ = 36°

Therefore, the angle of elevation of the sun from the ground to the top of a tree is 36°.

Check my steps and for part b, the professor wants us to show are work and I don't know how to solve it by hand.
Ugo [173]
Part a is correct.

Part b can be done a couple ways.
1) Use binomial distribution. p = 0.2, n = 144
P(x>3) = 1 - P(x=0) -p(x=1) -p(x=2) -p(x=3)
where
P(x=k) = (nCk)p^k (1-p)^{n-k}

2) Assume a normal distribution with mean = 28.2, stdev = 4.8
z = \frac{4 - 28.2}{4.8} = -5.04
Look up z-value in normal table to find probability.

Hope that helps.
