The answer is 58,650 and i am sure.........
I attached a photo of the work below :-)
Area of a trapezoid= [(a+b)÷2]h
1,224 in²= [(65.5 in+70.5in)÷2]h
1,224in²= (136÷2)h
1,224 in²= 68h
(1,224 in²÷68)= 68h÷68 (elimination)
h= 18 inches
The answer is D.
The angles shown are opposite interior angles meaning they are congruent. if you plug in 20 for x, they add up to be the same number, unlike the other options. so the answer is D
Well for a linear function you would use the formula y=mx+b
