How to:
a+b-mx=0
a+b=mx
(a+b)/x=m
Answer:
x = 10
Step-by-step explanation:
For the lines to be parallel, the two angles must have the same measure:
80 - x = 90 - 2x
x = 10 . . . . . . . . . add 2x-80
The value of x must be 10 to make the lines parallel.
C.
90 + 2x = 180
Solve that and x is answer
F(x)=3x+2
(FG)(x)=3(x+5)+2
=3x+15+2
=3x+17
