Need help on 12...have to find the area..teacher said to use pythagreoum(how ever u spell it) theorem

58

Step-by-step explanation:

you can find the height of this trapezoid by using the pythagorean theorem where the hypotenuse is 18 and one leg is 8 (33-25)

let x = height

+ =

= 324 - 64

= 260     therefore, x =

= ·  or  2

A = h x (sum of the bases)        

bases are 25 and 33

A = (2) ÷ 2)58

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
