### RD Sharma Solutions for Class 9 Maths Chapter 8 Lines and Angles Exercise 8.2 PDF

In geometry, we usually come across geometrical figures with angles having certain relations among themselves. In this Exercise 8.2, students will learn the details of the relations between the angles formed between the lines. Let us have a look at one example given below.

Example: OA and OB are opposite rays in the diagram below:

(i) If x = 250, what is the value of y?

(ii) If y = 350, what is the value of x?

Solution:

(i) Given: x = 25

From figure: ∠AOC and ∠BOC form a linear pair

Which implies, ∠AOC + ∠BOC = 1800

From the figure, ∠AOC = 2y + 5 and ∠BOC = 3x

∠AOC + ∠BOC = 1800

(2y + 5) + 3x = 180

(2y + 5) + 3 (25) = 180

2y + 5 + 75 = 180

2y + 80 = 180

2y = 100

y = 100/2 = 50

Therefore, y = 500

(ii) Given: y = 350

From figure: ∠AOC + ∠BOC = 180° (Linear pair angles)

(2y + 5) + 3x = 180

(2(35) + 5) + 3x = 180

75 + 3x = 180

3x = 105

x = 35

Therefore, x = 350
