isosceles triangle is four times the
third angle, what will be the measure
of all the three angles?​

Answer 1

Answer:

If each of two equal angles of on

isosceles triangle is four times the

third angle, what will be the measure

of all the three angles?

Answer 2

Step-by-step explanation:

let the 3rd angle = x

therefore 1st angle = 4x = 2nd angle

sum of all angles in a triangle =180

so, x+4x+4x=180

9x=180

x=180/9

x=20

1st angle =2nd angle =4x

=4(20)

=80

3rd angle =x

20
