Question

Find the length of the third side. If necessary, write in simplest radical form. 8 17

Answer 1

Answer:

9

Step-by-step explanation:

so we know that its a right triangle and 8 and $\sqrt{17}$ are not the hypotenuse.

the equation for this is $a^{2}$+$b^{2}$=$c^{2}$ with c being the hypotenuse.

$8^{2}$+$\sqrt{17} ^{2}$=$c^{2}$

64+17=$c^{2}$

81=c

$\sqrt{81}$=c

9=c

Answer 2

Answer:

Step-by-step explanation:

To make the use of Pythagoras's theorem clear

$C^{2}$ = $A^{2}$ + $B^{2}$

where C is they hypotenuse or Hyp

A is one side often called  the Adjacent side

B is the other side often called the Opposite side

when A = 8

and B = $\sqrt{17}$

then

$C^{2}$  = $8^{2}$ + $\sqrt{17} ^{2}$

$C^{2}$ = 64 + 17

$C^{2}$ = 81

C = $\sqrt{81}$

C = 9
