Question

the Vertical angle of an isosceles triangle is 110 degree what must be the size of each of its base angles​

Answer 1

Answer:35°

Step-by-step explanation:

110°+x+x=180°

2x=70°

Or=35°

Answer 2

In an isosceles triangle 2 sides are equal and the angles opposite to them are also equal

then both the base angles will be same

let the base angle be x

then,

110+x+x=180

2x=180-110

2x=70

x=35

therefore the base angles is 35°
