x = 31

Here we have 2 supplementary angles, meaning they both add up to 180.

Therfore we can derive the equation:


2x+9+3x+16 = 180

Next, we group like terms.


2x+3x+9+16 =180

Now, we combine like terms.


5x+25 = 180

Then, we move 25 to the right side.

5x = 155

Finally, we divide both sides by 5.


x = 31

Answer:

X = 31

Explanation:

180 = 2x + 9 + 3x +16

180 = 5x + 25

180 + -25 = 5x

155 = 5x

5x/5 = 0 (Cancel out)

155 /5x = 31

X = 31

Check math by :

2 x 31 = 62 + 9 = 71

3 x 31 = 93 + 16 = 109

109 + 71 = 180

Therefore, X = 31
