Answer:

24 Degrees

Step-by-step explanation:

Supplementary Angles are two angles with a sum of 180 degrees.

x+6+7x+30=180

8x+36=180

8x=144

18=x

Plug in 18 to angle A

18+6=24

24 degrees

Find the inverse function? I need help.

Tatiana [17]

Super easy. Take the function, and replace X with Y and Y with X. For example, if Y=12/x, then the inverse would be X=12/Y. Now solve for Y, so XY=12, the Y=12/x.
