Two angles of a triangle are equal and the third angle is greater than each of those angles by `30^@dot` Determine all the angle of the triangle.

Explanation

let in` /_\ABC`
equal angles `=x^@`
then 3rd angle`=(x+30)^@`
from angle some `x^@+x^@+(x+30)^@=180^@`

`x=50^@`
so1st angle`=2nd` angle`=50^@`
3rd angle`=80^@`
