What is the value of n

1 answer:

4 0

So firstly you are given the external angles, to find the internal angles, you do 180-133=47

180-142=38
the internal angles in a triangle add up to 180, therefore it is
47+38=85
180-85=95
because you have to find the external angle=n you then need to take 95 away from 180
180-95=85
so the answer is A
