Question

two adjacent angles on a straight line are in the ratio 5:4 find the measure of each angle​

Answer 1

hope it helps plz mark as brain list

Answer 2

sum of 2 adjasent angle in a strait lyn = 180°

given ratio between two adjasent angle = 5 : 4

let us denote dem with 5x and 4x

=> 5x + 4x = 180°

=> 9x = 180°

=> x = 180/9

=> x = 20°

hence the two adjasent angles r :-

5x = 5 × 20 = 100°

4x = 4 × 20 = 80°
