Question

In a isosceles triangle each of its base angle is 30 degree less than its remaining angles.Find the angles of triangke​

Answer 1

Hey ✌

Here is your answer

Let the three angles be a, b and c.

b and c are base angles.

angle b = angle C = angle a - 30°

Let angle a be 'x'.

x+x-30+x-30=180 (sum of angles of triangle is 180°,anglesum property of triangle)

3x-60=180

3x=180+60

x=240/3=80

Therfore,

Angle a = 80°

Angle b = 50°

Angle c = 50°
