What is the value of x

GarryVolchara [31]

<h2><u>We can solve it using trigonometric values.</u></h2>

<h3>So , <u> </u><u>sin</u><u> </u><u>θ</u><u> </u> = ( Perpendicular / Hypotenuese )</h3>

<h2><u>Given</u><u> </u></h2>

Perpendicular = x

Hypotenuese = 30

${ \sf{sin \: \: 45 {}^{ \degree} = \dfrac{1}{ \sqrt{2} } = \dfrac{x}{ 30} }}$

${ \sf{x = \dfrac{30}{ \sqrt{2} } }}$

<h2>∴ x ( Perpendicular)= 15√2 <u>Ans</u><u>.</u></h2>
