Answer 1

$\bf \huge {\underline {\underline \red{AnSwEr}}}$

⠀⠀⠀⠀⠀⠀

Given

⠀⠀⠀⠀⠀⠀

• l₁ || l₂

⠀⠀⠀⠀⠀⠀

To Calculate

⠀⠀⠀⠀⠀⠀

• Value of x

⠀⠀⠀⠀⠀⠀

Concept Used

⠀⠀⠀⠀⠀⠀

✭ Co - Interior Angle

⠀⠀⠀⠀⠀⠀

If the two lines are parallel, then co-interior angles add to give 180° and so are supplementary.

⠀⠀⠀⠀⠀⠀

Solution

⠀⠀⠀⠀⠀⠀

$\bf \implies (3x + 20) \degree + 2x\degree = 180\degree(co - interior \: angle$

⠀⠀⠀⠀⠀⠀

$\bf \implies3x + 20 + 2x = 180$

⠀⠀⠀⠀⠀⠀

$\bf \implies5x + 20 = 180$

⠀⠀⠀⠀⠀⠀

$\bf \implies5x = 180 - 20$

⠀⠀⠀⠀⠀⠀

$\bf \implies 5x = 160$

⠀⠀⠀⠀⠀⠀

$\bf \implies x = 160 \div 5$

⠀⠀⠀⠀⠀⠀

$\bf \implies x = 32 \degree$

⠀⠀⠀⠀⠀⠀

Hence, value of x is 32°.

⠀⠀⠀⠀⠀⠀

$\bf \implies3x + 20 + 2x = 180$
