The sum of two angles of a triangle is twice the third angle. Find the angles.
━━━━━━━━━━━━━━━━━━━━━━━━━
━━━━━━━━━━━━━━━━━━━━━━━━━
Let, the measure of third angle be x.
According to the question , each of the remaining two angles are twice of x.
Third angle = x
Each equal angle = 2x
Sum of all the triangles = 180°
x+2x+2x= 180°
5x= 180°
x=
x= 36°
Therefore,third angle= x=36°
Each Equal angle= 2x= 2× 36° = 72°
