Find the missing dimension of the following figure if the volume is equal to 550 yd3. 8 yd 9 yd 10 yd 11 yd

y = 1/2x + 5/2

P.S, this isn't geometry really. It's more like algebra :)

Step-by-step explanation:

Step 1: Find equation of line AB

m = (5 - 1)/(-2 - 0)

m = 4/-2

m = -2

y = -2x + 1

Step 2: Find slope of perpendicular line

Take the negative reciprocal of line AB

m = 1/2

y = 1/2x + b

Step 3: Find b

6 = 1/2(7) + b

6 = 7/2 + b

b = 5/2

Step 4: Rewrite perpendicular equation

y = 1/2x + 5/2

or

y = 0.5x + 2.5
