Question

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

Answer 1

Answer:

let the first angle be 4x

let the second angle be 5x

since, we know sum of two supplementary angle is 180

ATQ,

4x+5x=180

9x=180

x=180/9

x=20

so, first angle = 80

second angle = 100

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..!!!
