Question

Find x and y in the following figure
​

Answer 1

Answer:

X = 45 and y= 45+90

because y is the exteit angle

Answer 2

Answer:

x = 45,

y= 180-45= 135

Step-by-step explanation:

the given triangle is isosceles

so two sides are equal,

one of the sides is already 90

sum of all angles of a triangle is 180

so,

(90 + x + x) =180

90+2x = 180

x= (180-90)/2

x= 90/2

x = 45

sum of supplementary angles is 180,

so y= 180-x

y= 135

hope its clear enough
