Question

If the vertical angle of an isosceles triangle is 70degre what is the base angle

Answer 1

Answer:

vertical angle = 70°

let the base angles be x each(base angles in isosceles triangle are equal)

70°+2x = 180°(Angle sum property of triangle)

2x=180°-70°

2x=110°

x=110°/2

x=55°

Answer. The base angles are 55° each
