Hey There!
The formula to calculate for surface area is
2(wh + lw + lh)
Let's plug these numbers in.
2(7*20 + 15*7 + 15*20)
Calculate
7 * 20 = 140
15 * 7 = 105
15 * 20 = 300
Add these numbers up
300 + 105 + 140
= 545
Multiply 545 * 2 = 1090
Therefore, the surface area of the figure would be 1090in
Hope this helped!

Answer:
1. 23.59 feet
2. 32.9°
Step-by-step explanation:
1. See the diagram attached.
The man is 11 feet distance from the bottom of the tree.
And the angle of elevation from the man to the top of the tree is 65°.
Now, we need to approximate the height of the tree,
Using the trigonometry, we can write
⇒ h = 11 tan 65° = 23.59 feet (Approx.) (Answer)
2. See the diagram attached.
From the given right triangle the hypotenuse is 25 feet and the base is 21 feet.
And the angle between the hypotenuse and the base is the pitch of the ram of a NASCAR turn.
Using trigonometry, we can write
