Explanation:
Hey there! Hope I can help!
If the angle measures 120, then the angle vertical to it also equals 120.
Triangles always add up to 180 total degrees, so 180-120=60
This means the two angles combined equal 60.
so…
(2x+3)+(3x+2)=60
COMBINE LIKE TERMS
5x+5=60
SUBTRACT 5 BOTH SIDES
5x=55
DIVIDE BY 5 ON BOTH SIDES
x=11
now plug x in
2x+3 ——> 2(11) +3 which equals 25
THE ANSWER IS 25 for ANGLE A and
