Question

Each equal angle of an isosceles triangle is four times the third unequal angle. Find the measures of all angles of the triangle.

Answer 1

Answer:

angle 1 =20

angle 2 and 3 = 80

Step-by-step explanation:

unequal angle take as x and equal angles as 4x each add

x+4x+4x = 180

9x= 180

x=180/9

x=20

Answer 2

Answer:

angle 1 =20

angle 2 and 3 = 80

Step-by-step explanation:

unequal angle take as x and equal angles as 4x each add

x+4x+4x = 180

9x= 180

x=180/9

x=20
