Brainliest maybe? Trying to get to next rank. Sorry to ask.
The right answer is the 2nd one.
It's using the quadratic equation
Come on too easy my friend
Remember
the exterior angle=sum of the other 2 interior anlges
therfor
(one that is less pointy triangle)
2x+3x=135
5x=135
x=27
2*27=54
3*27=81
the interior angles are 54 and 81 and x=27
other pointier one with 3x-1 on it
12+3x-1=167
11+3x=167
minus 11
3x=156
divide 3
x=52
sub
3*52=156
156-1=155
missin angle is 155, x=52
