30-a+125-2a=180°
175+3a=180°
3a= 180-175
3a= 5
a= 5/3= 1.666

This answer is incorrect
i know it is + not minus sign mistake
first we arange the equation 125+2a & 30-a = a 125+30+a=180 then a=155-180 = 25 ans is a=25
(30-a)+(125+2a) = 180° [supplementary angles]

Supplementary angles sum up to 180deg.
30-a+125+2a=180
a+155=180
a=25 deg
