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°
