It costs a family $216 to refinish a wood floor. They want to refinish floor in a larger room. The ratio of lengths of corresponding sides 3/4. How much would it cost to refinish wood floor in a larger room?

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

r = 78539458390583095803458309458039485093485 or just 3
