Question

What is the value of n?

Answer 1

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

n = (180 - 133) + (180 - 142)
n = 47 + 38
n = 85

Answer
C. 85

Answer 2

You would first subtract 133 from 180 and get 47
then subtract 142 from 180 and get 38
then add 47 and 38 together to get 85
then subtract 85 from 180 to get 95
95 would be the value next to N
subtract 95 from 180 and you'll get 85 as your N angle
