## Class 7 Maths NCERT Solutions Chapter 6 The Triangle and its Properties Ex 6.2

**Ex 6.2 Class 7 Maths Question 1.**

Find the value of the unknown exterior angle x in the following diagrams:

**Solution:**

Since, in a triangle an exterior angle is equal to the sum of the two interior opposite angles, therefore,

- x = 50°+ 70° = 120°
- x = 65°+ 45° = 110°
- x = 30°+ 40°= 70°
- x = 60° + 60° = 120c
- x = 50° + 50° = 100c
- x = 30°+ 60° = 90°

**Ex 6.2 Class 7 Maths Question 2.**
