Question

Find the unknown angles in the given triangle​

Answer 1

Answer:

x= 60 because external opposite angle of triangle ate congruent

Answer 2

Answer:

x = 60 °{alternate angle }

this is isosceles triangle

let another two angle be y

60°+y +y = 180

60° +2y =180

2y =180-60

2y =120

y=120/2

y= 60

then 60 + y = 180 y =180-60

y = 120
