Question

if each of the two equal angles of an isosceles triangle is four times the third angle, find the three angle of the triangle ​

Answer 1

Answer:

20° , 80° , 80°

Step-by-step explanation:

the angles can be  a , 4a , 4a

9a = 180

a = 20

the angles can be  20° , 80° , 80°

Answer 2

let one side of triangle be a

Then according to question

the sides are a, 4a, 4a

We know that perimeter of a triangle =180

=>a+4a+4a=180

9a=180

a=180/9

a=20

Therefore the sides are

20

4*20=80

4*20=80
