85o
95o

42o

Answer 1

85

Answer 2

here's a hint...x is in a triangle...therefore the sum of the angles INSIDE the triangle should equal 180

does that help?

Answer 3

yeah but then why is 127 there what do i do with that

Answer 4

all triangles add up to 180 so add the two numbers in the triangle then subtract 180.

Answer 5

@tayla there are two approaches to do the question...one as @lgbasallote and one is that in every such question where exterior angle of triangle is given then use

Answer 6

but both approaches are one and the same

Answer 7

okay so either way it is 80

Answer 8

it's not 80

Answer 9

i meant 85

Answer 10

yup..

Answer 11

okay
