Question

Find the value of x . (Do not round until the final answer . Then round to the nearest tenth as needed .)

Answer 1

According to the given image, x is the radius of the circle.

So, we can find x using Pythagorean's Theorem in the following right triangle.

Where x is the hypothenuse.

`\begin{gathered} x^2=5.3^2+4^2 \\ x=\sqrt[]{28.09+16} \\ x=\sqrt[]{44.09}\approx6.6 \end{gathered}`

Hence, x is 6.6, approximately.
