Question

if each of the two equal angles of an isosceles triangle is 4 times the third angle find the three angle of the triangle

Answer 1

let other angle be x
now a/q
equal angles are 4x and 4x
4x+4x+x=180
9x=180
x=180/9=20
angles are 80° .80°and20°

Answer 2

Answer:

80, 80, 20

Step-by-step explanation:

Let the other angle be x

isosceles property= 2 angles are always equal

So, 4x, 4x, x are the angles

Angle sum property=

4x+4x+x= 180

9x= 180

x= 180/9

 = 20

4x= 20 into 4

   = 80

Therefore= the angles are 80, 80 and 20
