Answer: 27


Step-by-step explanation:


(3x +9) is on a straight line with the right angle so we know

Answer:

x=27

Step-by-step explanation:

3x+9 is a right angle because 3x+9 + a right angle make a straight line

3x+9 +90 = 180

Subtract 90 from each side

3x+9 = 90

We now can solve for x

3x+9-9 = 90-9

3x = 81

Divide each side by 3

3x/3 = 81/3

x=27
