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

Hello! answer: 58
Step-by-step explanation:
40 × 40 = 1600
42 × 42 = 1764
1600 + 1764 = 3364
√3364 = 58
58 × 58 = 3364 therefore c = 58 Hope that helps!
Answer:
39
Step-by-step explanation:
The angles are equal. This means that the triangle is equilateral and all the sides are equal to each other.
Set any two sides equal to each other.
2x - 3 = x + 5
x - 3 = 5
x = 8
Now substitute this x value into all the sides and add the numbers up.
2(8) - 3 = 16 - 3 = 13
So we know all 3 sides equal 13.
13 * 3 = 39
