Answer:
x=20
3x= 3(20)=60
4x= 4(20)=80
Step-by-step explanation:
The angles CD is 90 degrees because the small square indicates
it. Angles AD are a straight angle, therefore all the other angles within A to D, must equal 180 degree. (straight line/angle=180 degrees).
so AB + 70+ 90= 180 degrees
AB= 180 -70-90
AB=20
x=20
3x= 3(20)=60
4x= 4(20)=80
I think it is 60.05 if not im sorry

Answer: x + 27 = 17
Step-by-step explanation:
4(x+3) = 4x + 12
3(5-x) = 15 - 3x
4x-3x+12+15
x+27
