Plz help me find x ASAP

x=74.5

Step-by-step explanation:

31+2x=180

Every inside of a triangle is 180 degrees

The next step is to subtract 31 from both sides to get

2x=149

divide both sides by two to isolate the variable to get

x=74.5

Hope this helps. If you have any follow-up questions, feel free to ask.

Have a great day! :)

the answer is (2x+8)²= 16

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
