Respuesta :

Since the two sides are equal , that is 7=7
=> the given triangle is an isosceles triangle , because two sides are equal
And in an isosceles triangle base angles are equal => 66 = 66
So by angle sum property
66+66+x =180
=>x= 180-132
=>x=48
Hope this helps u..!!!
It’s 48 because since it’s an isosceles triangle, the other angle that is NOT x would also be 66.
66+66=132
180-132=48
