The great pyramid has a height of about 480.7 feet and base edges about 756 feet. the base is almost square. find the approximate volume of this pyramid. a) 571,530 ft b) 90,000,000 ft c) 91,579,118.4 ft d) 274,737,355.2 ft is it a, b, c, or d?

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
