Question

For the phone right triangle find the side length X round your answer to the nearest hundredth

Answer 1

Given: The figure below

To Determine: The value of x in the figure above

Applying the Pythagoras theorem, the square of the hypothenuse is equal to the sum of the squares of the other sides. The hypothenuse is the side facing the right angle or the longest side

From the given triangle, the hypothenuse is 10.

Let us apply the Pythagoras theorem

`10^2=x^2+6^2`
`\begin{gathered} 100=x^2+36 \\ 100-36=x^2 \\ 64=x^2 \\ x^2=64 \\ x=\sqrt[]{64} \\ x=8 \end{gathered}`

Hence:

x = 8
