Question

in the given figure find the value of X and y​

Answer 1

Answer:

y = 40 degree and x = 100 degree

Step-by-step explanation:

two sides are equal so angels must be equal ( isosceles triangle ) so, y =40 degree and x= 180 - (40 + 40) = 180- 80= 100 degree

Answer 2

Answer:

x=100°

y=40°

Step-by-step explanation:

As AB=AC

angle ABC=y=40(angle opposite to equal sides are equal)

in ∆ABC

x+y+40=180(angle sum property)

x+40+40=180

x+80=180

x=180-80

x=100°
