Gina looked at the triangle above and noticed that two acute angles added together equals to 90o. 53 + 37 = 90. Using this info, she wrote C + G = 90. She concluded: Since G = 90 - C, sin G = sin (90 - C) and cos G = cos (90 - C) Since C = 90 - G, sin C = sin (90 - G) and cos C = cos (90 - G) Is her conclusion true?

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

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
