Answer 1

Answer:

hi mate

Step-by-step explanation:

The other angle must me 55+55+x = 180

110+x = 180

x = 180-110

x= 70 degree

Answer 2

Step-by-step explanation:

In an isosceles triangle the base angles are equal

:. if one equal angle is 55 the other base angle will be 55

now, by angle sum property,

55+55+x (since we don't know the value) =180

:. 110+x=180

x=180-110

x=70°

Therefore, the angles are 55;55&70

Hope this helps
