Does anyone know how to solve this? Please help

Answer:
m = 36°
n = 27°
Step-by-step explanation:
We know that 126° + 2n = 180° as n is the base angle of an isosceles triangle.
n = 27°
Now let's find the complementary angle of 126°, that will also be an angle intern to the right triangle:
180° - 126° = 54°
m will be equal to:
m = 90° - 54° = 36°
