Question

Plz help in a rush!!!!!!!!!!

Answer 1

Your answer is 4.7

Using the Pythagorean Theorem, you can find the length of the missing side:

$a^{2}+b^{2}=c^{2}\\(3)^{2}+b^{2}=(5.6)^{2}\\9+b^{2}=31.36\\b^{2}=22.36\\b=\pm \sqrt{22.36}$
Length cannot be negative, so your answer is:
$b=\sqrt{22.36}=4.728636...\\\\b=4.7$

Answer 2

4.7 is your answer. Good Luck!
