Answer 2

Answer:

(I) Let angle third = z

Now, 120+ z = 180 (linear pair)

therefore, angel z = 60

but here two sides of triangle are equal

so, angel y=angel z = 60 (opposite angel of equal side are equal)

we know that the exterior angle is equal too opposite of two interior angle

so, x+ y + z = 180 ( angel sum property of triangle)

= x + 60+ 60 = 180

= x = 180-120 = 60

therefore, x= 60 , y= 60 and z =60
