Answer:
M = 22
N = 34
Explanation:
To find the value of m, you first need to subtract 180 from 112, which gives you 68. The reason we do this is because it is a straight angle and equals 180 degrees in total. As you know, a triangle equals 180 degrees, meaning you can subtract 180 from 90 and 68, getting you 22.
To find the value of n, you need to understand the properties of an isosceles triangle, more specifically that the two base angles are congruent to each other. So if you do 180-112, you get 68. However, this is not your final answer as that is the measurement for BOTH angles. Now you have to do 68/2, giving ou 34 as your final answer.
Of course, you can check by adding up all of the angles in each triangle and making sure it equals 180 degrees!
