Answer:

x = 18

A = 110

Explanation:

Angles A and B are supplementary angles so they add to 180 degrees

A + B = 180

5x+20 + 9x -92 = 180

Combine like terms

14x -72 = 180

Add 72 to each side

14x-72+72 = 180+72

14x = 252

Divide each side by 14

14x/14 = 252/14

x =18

A = 5x+20

= 5*18 +20

=90 +20

= 110
