Question

find angle x and y step by step​

Answer 1

Answer:

sum of two interior angles = exterior angle

Answer 2

Answer:

x= 60

y= 60

Step-by-step explanation:

external angle 120

180-120= 60

It's an isosceles triangle so adjacent angles of opposite sides are equal.

y = 60

now

x+y+60=180

x+120=180

x= 60
