2x+y+125=180 ______(1)
2x+y = 180-125= 55_____(1)
2x+y= 55____(1)

now sum of angles in a triangle equals 180
x+2y + 2x+y +90 = 180
3x +3y =180-90=90
3x +3y=90
x+y=30______(2)

minus (2) from (1)
2x-x =55-30
x= 25 °
sub x=25° in eqn (2)
25+y=30
y=30-25= 5
x= 25 and y= 5


if it's correct please make it the brainliest answer thnkx
