Answer 2

Given :

Straight line

means sum of angles = 180°

$\\ \large \sf \star \: \: linear \: \: pair :$

Sum of angles along a straight line = 180°

Solving

• 1 angle = 5x

• 2 angle = 4x

$\\ \large \implies \tt \: 5x + 4x = 180 \degree \\ \\ \large \implies \tt \: 9x = 180 \degree \\ \\ \large \tt \implies \: x = \frac{180 \degree}{9} \\ \\ \large \boxed{ \sf \therefore \: \: x = 20 \degree}$

Here we got ,

• Value of 'x'

$\\ \large \sf \star \: \underline{angles \: } :$

• 5x = 5(20) = 100°

• 4x = 4(20) = 80°

_______________________________________

$\\ \large \sf \star \: \underline{check} :$

Property of linear pair -

$\\ \large \implies \tt \: 5x + 4x = 180 \degree \\ \\ \large \implies \tt \: 100 \degree + 80 \degree = 180 \degree \\ \\ \large \tt \implies \: 180 \degree = 180 \degree$
