Hi there!

Every triangle's angles add up to 180.

63+86=149

180-149=31

Making the unknown angle 31 degrees.

Since what were looking for is a supplementary angle, it also adds up to 180.

180-31=149

X=149, your answer is A

Step-by-step explanation: for the exterior angle theorem you add the 63 and the 86 to find the other "x". Hope I Helped!!
