The value of angle C in the triangle is 55°

An isosceles triangle is a type of triangle that has two equal sides and two corresponding equal angles.

The sign on the triangle shows that it is an isosceles triangle. This means that angle A is equal to angle C.

The sum of angles in a triangle is 180°.

let angle C be x

x+x + 70 = 180

2x + 70 = 180

2x = 180 - 70

2x = 110

x = 110/2

x = 55°

Therefore , the value of angle C is 55°
