Question

ratio of two angles of a linear pair of angles is 4:5 .find the magnitude of both the angles.​

Answer 1

Answer:

Let the first angle be 4x

second angle= 5x

sum of linear angles = 180

ATQ

4x + 5x= 180

9x= 180

x= 20.

first angle = 4x= 80

second angle = 5x= 100.

Answer 2

Answer:

Step-by-step explanation:

So Take Both The Angles As 4x and 5x

Since We Know That The Angles In A Linear  Pair Add Up To 180*

We Can Form An Equation

Which Is

4x + 5x = 180

9x = 180

Dividing 9 on both sides we get

9x/9 = 180/9

x = 20

Angle1 = 4 * 20 = 80*

Angle2 = 5 * 20 = 100*
