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?
(image will be uploaded soon)
(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
