Answer:
m = n = 20
Explanation:
Here, we want to find the missing side lengths
For a 45-45 triangle, the lengths have a side ratio of;
1:1: √2
We should understand that the triangle is isosceles ( opposite and adjacent are equal)
So n = m
So what we just need to do here is divide 20 √2 by √2
Mathematically, that would be;
20 √2/√2 = 20
