Answer:

C

Step-by-step explanation:

its A cause 70 and (x+20) are Consecutive exterior angles and that means they are supplimentary (they both have a sum of 180)

180-70=110

but you cant use 110 because 110 +20= 130 which sums up to be more than 180 so you subtract 20.

110-20= 90

and there you go!

hope i helped :)
