Find the values of x and y in Fig. 6.37. Plan a Strategy

Formula Used/Theory:-


→ Exterior angle is equal to sum of interior opposite angles


In the bigger triangle


By exterior angle property


y = 30° + 45° = 75°


In smaller triangle


By exterior angle property


x = 50° + 30° = 80°


Result:- The value of x comes out to be 80°


The value of y comes out to be 75°
