Question

Each of the two equal angles of an isosceles triangle is four times the third angle. Find the angles of the triangle.

Answer 1

Answer:

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= 180O 9x= 180 X= 180/9 = 20 4x= 20 into 4 = 80 Therefore= the angles are 80, 80 and 20

Answer 2

Answer:

let the 3 angle be x

then two equal angle= 4x

4x+ 4x+ x=180

x=280/9=20

other two 4×20=80
