Question

what is the value of x ​

Answer 1

We can solve it using trigonometric values.

So , sin θ = ( Perpendicular / Hypotenuese )

Given

Perpendicular = x

Hypotenuese = 30

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

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

∴ x ( Perpendicular)= 15√2 Ans.

Answer 2

Answer:

15√2 is your answer

Step-by-step explanation:

for your question

relation between perpendicular and hypotenuse is given by sin angle

sin45=p/h

sin45=x/30

x=sin45×30=15√2
