Question

What are the values of m and n?

Answer 1

I got n=21 and for m i got m=45 and this is how i subtracted 180-138 then i got 42 and i divided 42/2 because if the right angle was n the one on the left side is n also and for the m i did 180-90 because 90 was the right angle in the corner so 180-90 is 90 then i divided it by 2 because their is 2 m so 90/2m would be 45

~hope that helps :)

Answer 2

180 - 138 = 42°
90 + 42 = 132°
180 - 132 = 42° = m
-
90 + 42 + 2n = 180
132 + 2n = 180
- 132
2n = 48
÷ 2
n = 24°
