Answer:

Explanation:

well what is the formula of a triangle 1/2b*h then you take the base times the height then by one half to get your sender

The set of lengths of sides that forms a right triangle will be the one that satisfies Pythagoras' theorem, that is


\begin{gathered} a^2+b^2=c^2 \\ \text{ Where a and b are the legs and c is the hypotenuse of the right triangle } \end{gathered}

So, you have

Option A


\begin{gathered} a^2+b^2=c^2 \\ (7)^2+(14)^2=(15)^2 \\ 49+196=225 \\ 245\\e225 \end{gathered}

Option B


\begin{gathered} a^2+b^2=c^2 \\ (8)^2+(16)^2=(18)^2 \\ 64+256=324 \\ 309\\e324 \end{gathered}

Option C


\begin{gathered} a^2+b^2=c^2 \\ (8)^2+(15)^2=(17)^2 \\ 64+225=289 \\ 289=289 \end{gathered}

Option D


\begin{gathered} a^2+b^2=c^2 \\ (9)^2+(12)^2=(17)^2 \\ 81+144=289 \\ 225\\e289 \end{gathered}

Therefore, the set of side lengths that make up a right triangle is


C.\mleft(8,15,17\mright)

and the correct answer is C.
