The total would be 180 degrees because angles on a straight line would always add up to 180.
(3x+31)+(2x-6)=180
5x+25=180
-25 -25
5x=155
/5 /5
x=31

Step-by-step explanation:
Answer:
r = 11
Step-by-step explanation:
mDG and mGM must add up to mDM
Step 1: Set up equation
mDG + mGM = mDM
r + 5 + 3r - 14 = 35
Step 2: Solve for <em>r</em>
<u>Combine like terms:</u> 4r - 9 = 35
<u>Add 9 to both sides:</u> 4r = 44
<u>Divide both sides by 4:</u> r = 11
Answer:
