Step-by-step explanation:

The formula used in calculating the length of the base of a pyramid is tan(∅) = height/base

To calculate the length of the base of the pyramid,

tan(42°) = 0.9004

Since the height is 71 meters we then multiply it by 2

2 x 71 = 142 meters

Since tan(∅) = height/base

0.9004 = 142/X

We cross multiply

0.9004x = 142

we divide both sides by 0.9004

X = 142/0.9004

X = 157.7

X = 158 feat
