Answer:
m = 20 and n = 35
Explanation:
The triangle on the right has 2 congruent sides and is isosceles
Thus the 2 base angles are congruent, that is
n =
=
= 35
The external angle of a triangle is equal to the sum of the 2 opposite internal angles.
110 is an external angle to the triangle on the left, thus
m + 90 = 110 ( subtract 90 from both sides )
m = 20
