What is the value of x?

Svetllana [295]

Answer:

x = 4

Step-by-step explanation:

ΔTRQ is an isosceles right triangle, so if we find the value of RT then the value of 'x' will be the same

We can find RT by creating a proportion based on the ratio of sides in a 30-60-90° triangle which, respectively, is 1 : $\sqrt{3}$ : 2

2 $\sqrt{3}$ /RT = $\sqrt{3}$ /2

cross-multiply:

$\sqrt{3}$ · RT = 4 $\sqrt{3}$

RT = 4

Therefore, x = 4

The area of circle K when c=24x^2 pi

Gala2k [10]

Answer: $\frac{\sqrt{6}\sqrt{\pi }\sqrt{Kc}}{12\pi },\:x=-\frac{\sqrt{6}\sqrt{\pi }\sqrt{Kc}}{12\pi }$

Step-by-step explanation:

$c=24x^2 pi$

Switch sides:

$24x^2\pi =Kc$

divide both sides by $24\pi$

$\frac{24x^2\pi }{24\pi }=\frac{Kc}{24\pi }$

simplify:

$x^2=\frac{Kc}{24\pi }$

$x^2=\frac{Kc}{24\pi }$ $x=\sqrt{\frac{Kc}{24\pi }},\:x=-\sqrt{\frac{Kc}{24\pi }}$

answer: $x=\frac{\sqrt{6}\sqrt{\pi }\sqrt{Kc}}{12\pi },\:x=-\frac{\sqrt{6}\sqrt{\pi }\sqrt{Kc}}{12\pi }$

i hope it's help!
