Question

Two angles which are supplementary to each other are in ratio 4:5 then find out the two angles ​

Answer 1

Given the angles are supplement to each other

Hence sum of those two angles is = 180 degrees

Two angles are in ratio = 4:5

let 1st angle be =4x

2nd angle be =5x

Now 4x +5x = 180 degrees

9x = 180

x = 180/9

x = 20

1st angle = 4 ( 20) = 80 degrees

2nd angle = 5(20)= 100 degrees

Two angles which are supplementary to each other are in ratio 4:5 then find out the two angles

$\huge\bigstar\huge\tt\underline\red{ᴀɴsᴡᴇʀ }\bigstar$

Let the first angle be 4x

let the second angle be 5x

➜The sum of supplement angle is 180°

so,4x +5x=180

9x=180

x=20°

➙ first angle =4x=4*20=80°

➙second angle =5x=5*20=100°

Hope it helps you..!!!
