Class 7 - Mathematics - Unit 5: Lines And Angles - Problems and Solutions
Question. 98
Measures (in degrees) of two supplementary angles are consecutive odd integers. Find the angles.
Answer:
89°, 91°
Detailed Answer with Explanation:
Let angles = x, x+2. Since supplementary: x + (x+2) = 180 ⇒ 2x + 2 = 180 ⇒ 2x = 178 ⇒ x = 89. Angles are 89° and 91°.
