In Fig. 6.40, find the values of x, y and z.


Answer :

Formula Used/Theory:-


Angle sum property


Sum of all angles of triangle is 180°


Exterior angle is equal to sum of interior opposite angles


In Δ ABC


By angle sum property


A + B + C = 180°


90° + 60° + z = 180°


z = 180° - 150°


z = 30°


By exterior angle property


y = 60° + 60° = 120°


By exterior angle property


x = 30° + z


x = 30° + 30° = 60°


Result:- The value of x;y;z is 60°;120°;30°
