Question

in an isosceles triangle the equal angles are one fourth of vertical angle find the equal angles​

Answer 1

Answer:

the angles are 80, 80, 20.

Step-by-step explanation:

Let the equal angle be x and vertical angle be x/ 4

Sum of the angles in a triangle = 180

x +x+x/4=180

4x+4x+x=180×4

9x = 180×4

x=20×4

x=80

one fourth of x=x/4=20

plzz mark me as brainlist..... huge request

Answer 2

Answer:

80 80 20

Step-by-step explanation:

angle sum property

x+x+x/4=180

(9x)/4=180

9x=720

x=720/9

x=80

two side are eq so

1st=80

2nd=80

3rd=80+80+x=180

160+x=180

20=x
