Question

Find x and y for my question.

Answer 1

angle B = angle C =x,

x+x+50°=180°,

2x=130°,

then
x=65°,

now
x+y=180°,

then
65°+y=180°,

then
y=180°-65°,

y=115°

Answer 2

Angle BAC = 50° ....vertically opposite angles

Angle ABC= 65° ...,.angle sum property of triangle and isosceles triangle theorem



x= 65°
Y = 115° .....remote exterior angles
