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°
