since total addition of all three angles of triangle is 180
hence 2x-7+x+25+3x+12= 180
6x+ 30=180
6x=180-30
6x=150
x=150/6
x=25
hence first angle 2×25-7=43
second angle 25+25=50
third angle 3×25+12=87
hence 2x-7+x+25+3x+12= 180
6x+ 30=180
6x=180-30
6x=150
x=150/6
x=25
hence first angle 2×25-7=43
second angle 25+25=50
third angle 3×25+12=87
