Both angles together 90°

So

(9x + 5) + (3x + 1) = 90

12x + 6 = 90

12x = 84

12x/12 = 84/12

x = 7

(9x + 5) + (3x + 1) = 90

12x + 6 = 90

12x = 84

x = 7

The two angles together are 90° so...

(9x + 5) + (3x + 1) = 90
9x + 5 +3x + 1 = 90
12x + 6 = 90
12x = 84
x = 7

answer is x=7°

(9x+5)+( 3x+1)=90
12x+6=90
12x=84
x=7

12x + 6 = 90
12x = 84
x= 7
