Question

Can anyone help me find the unknown side length in this right triangle.

Answer 1

Answer:

9sqrd= 81

12sprd= 144

144+81= 225

$\sqrt{225}$= 15

so c=15

ps. use Pythagoras to help you.  

Answer 2

Answer:

$c=15$

Step-by-step explanation:

You can use Pythagoras theorem to find the value of c

Formula to find the hypotenuse:

$c=\sqrt{a^{2}+b^{2} }$

The value of a in the formula will be the height & the value for b in the formula is the base.

Now, add the values in the formula:

$c=\sqrt{9^{2}+12^{2} }$

$c=\sqrt{81+144 }$

$c=\sqrt{225}$

$c=15.96871942$

You can simply say that:

$c=15$

I hope this helps :)
