B) x=14
Step-by-step explanation:
Since sine and cosine are equal, the angles must be complementary.
3x + 10 + x + 24 = 90
4x + 34 = 90
4x = 56
x = 14
your welcome and everyone is smart some just dont know one of the answers
363 square inches
step-by-step explanation:
surface area of a pyramid is b + 1/2ph
b is the area of the base: 11 x 11 = 121
p is the perimeter of the base: 11 + 11 + 11 + 11 = 44
h is the height of the pyramid: 11
121 + 1/2(44)(11)
121 + 242
363
