Question

two angles of a triangle are equal and the third angle is greater than each of those angle by 30 degree determine all the angles of the triangle

Answer 1

let the equal angle be x
x+x+x+30°=180°{sum of all angles of trngle is 180}
3x+30°=180°
3x=180°-30°
3x=150°
x=150°\3
x=50°

hence, the equal angle is 50°
third angle=50°+30°=80°

Answer 2

let equal angle be x then
third angle equal x+30 degree
we know that angle sum property of triangle
x+x+x+30=180
3x=150
X=50 degree and third angle equal 80 degree
