Question

The vertical angle of an isoceles triangle is three times the sum of its base angles. find each angle.​

Answer 1

Answer:We know that in isosceles triangle that the opposite angles are equal. Then here the If the vertical angle be x then the base angle will be 3x and the opposite angle will be 3x so we got three angles but we need to find the value of x

x+3x+3x=180

7x=180

X=180/7

X=25.714

Then 3×25.714=77.142
