Question

If a pair of suplementary angles are in the ratio 4:5 then find the smallest angle.

Answer 1

Answer:

80 degrees

Step-by-step explanation:

let the common multiple be x

therefore angles are 4x and 5x

now sum of supplementary angles is 180

therefore 4x + 5x = 180

9x = 180

x = 180 / 9

x = 20

therefore smallest angle is 4x = 4(20) = 80 degrees
