Q1: Two supplementary angles are in …

Let the two supplementary angle be 4x and 5x As we know that the sum of supplementary angle is 180° So,4x + 5x= 180° 9x=180° x=180°/9 x=20° So 1st angle = 4×20° =80° and 2nd angle = 5×20° =100°

Let angles are 4x & 5x. ∴ Angles are supplementary
∴ 4x + 5x = 180°
⇒ 9x = 180°
⇒ x = 180°/9 = 20°
∴ Angles are 4 × 20° , 5 × 20°
⇒ 80° & 100°
