Answer:
x = 30
Step-by-step explanation:
If A parallel to B , then
2x and 4x are same- side interior angles and sum to 180° , that is
2x + 4x = 180
6x = 180 ( divide both sides by 6 )
15.75 is 6.3% of 250.
Formula:[Percentage] x [Number Given] = [New number]
can be said as " divided by ", so the ? is .
D=9
A=pie*radius^2
=3.14*9/2*9/2
=63.58
=64
