Question

plzz tell me the answer​

Answer 1

In the figure 6.138 :-

$\rm\huge\green{\underline{\underline{Given :- }}}$

• $\bf{l {\parallel} m {\parallel} n }$
• $\bf{\angle}x \:: {\angle} y = 3:2$

$\bf\huge\pink{\underline{\underline{To find :-}}}$

• $\bf{\angle} z = ??$

$\bf\huge\blue{\underline{\underline{ Solution :- }}}$

Here, we know that adjacent angles are 180°

$\bf{So, \:let's\: say\: that\:{\angle} x\: and \:{\angle}y = 3a \:and \:2a }$

According to the question,

$\bf{\therefore}{ 3a + 2a = 180°}$

=> 5a = 180° ( dividing both side by 5)

$\bf\orange{\underline{\bold{<strong> </strong><strong> </strong><strong> </strong><strong>=</strong><strong>></strong><strong> </strong><strong>a</strong><strong> </strong><strong>=</strong><strong> </strong><strong>3</strong><strong>6</strong><strong>°</strong><strong> </strong>}}}$

$\bf\purple{\underline{\angle{x = 3a = 3(36)° = 108°}}}$

$\bf\green{\therefore{\underline{\underline{\angle{z \: will \: also \: be \: 108° (opposite \:angles\: are \:equal) }}}}}$

Answer 2

the answer to this que is 108 degree.

If u want explanation plz tell me
