Answer:
Correct answer: a = 40 feet
Step-by-step explanation:
Given:
V = 19,200 feet³ volume of the sculpture
H = 36 feet height of the sculpture
a = ? side length of the square base
The formula for calculating the volume of a pyramid is:
V = B H / 3 ⇒ B = 3 V / H
B = 3 · 19,200 / 36 = 19,200 / 12 = 1,600
B = a²
a² = 1,600 ⇒ a = √1,600 = 40 feet
a = 40 feet
God is with you!!!
B. 30°
By remote interior angle theorem:
100° = x + 70°
100° - 70° = x
30° = x
x = 30°
