Find the value of x that will allow you to prove that CD below is parallel to EF if the measure of <1 is (3x+30) and the measure of <2 is 81 (the figure may not be drawn to scale

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3

step-by-step explanation:

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
