Answer:
[tex] x = 30.5 [/tex]
Step-by-step explanation:
Two angles are supplementary when they add up to 180°.
So we know that:
[tex] C + D = 180[/tex]
Supplanting we get:
[tex] (3x-44) + (5x-20) = 180 [/tex]
We add up the X's.
[tex] 8x-44-20 = 180 [/tex]
[tex] 8x-64 = 180 [/tex]
Then we send 64 to the other side adding:
[tex] 8x = 180+64 [/tex]
[tex] 8x = 180+64 [/tex]
[tex] 8x = 244 [/tex]
And then the 8 goes dividing:
[tex] x = 244 : 8[/tex]
[tex] x = 30.5 [/tex]
