Let 1 and 3 be 1x and 3x
We know that exterior angle if a triangle is equal to its opposite interior angles
So that,
1x+3xis equal to 180
4xis equal to 180 now
X is equal to 180 divide by 4 and value of x is 45
Now we shall put value of x
1x is equal to 1 multiply 45 equal to 45
3x is equal to 3 multiply by 45 equal to 135.
