Answer 15

okay so just know that on part 1b, the answer is not a (91) and 2 part b is not c ( the answer is probably a)

Answer 16

Make a side-view of the pyramid, and drop a perpendicular.

let the side of the base be 2x, (that way I don't have fractions in my variable)

in the right-angled triangle
tan 52° = 147/x
x = 147/tan52
= ...
then base side
= 2x
= ....
