The exterior angle of a triangle is 50 degree & interior oppositeangle are in the ratio 2:3, find the three angles of thetriangle?​

Answer»

Answer:

As we KNOW the a theorem that the exterior angle is the sum up of two interior OPPOSITE ANGLES so in here this condition 2:3

let this ratio be as 2x and 3x where x is any constant that we gotta find here

then Acc. to theorem 2x + 3x = 50

x=10

then angles will be

2 * 10= 20

3 * 10= 30 and third angle by angle sum PROPERTY of triangle that sum of all angles is 180 degrees

then third angle is 180 -(20+ 30) = 130 degrees

so angles are 20, 30 and 130 in degree
