Question

if two supplementary angles are in the ratio 4:5 then find the angles

Answer 1

Hey mate !!!   Answer :-  Given ,   Two supplementary angles are in the ratio of 4:5   We know that sum of supplementary angles are 180°  Let the angles be 4x and 5x respectively.  Then ,  ⇒4x + 5x = 180°  ⇒9x = 180°  ⇒x = 180/9   ⇒x = 20°  Now , the angles are   ⇒ 4x = 4× 20° = 80° And   ⇒5x = 5 × 20° = 100°   ∴the angles are 80° And 100°.  Hope it helps dear °Δ°
