Class 7 - Mathematics - Unit 5: Lines And Angles - Problems and Solutions
Question. 97
Two angles are making a linear pair. If one of them is one-third of the other, find the angles.
Answer:
45°, 135°
Detailed Answer with Explanation:
Let angles = x and 3x. Since linear pair = 180°, x + 3x = 180 ⇒ 4x = 180 ⇒ x = 45. Thus, angles are 45° and 135°.
