Can Sumone Heeeeeeelp Meee With Thiiiis Its Homework And Im About To Give Uup Like This Just Question 1 And Im Already Tired Pleeaaseeeee class=

Answer :

Answer: C— 9 m

Steps:
a^2 + b^2 = c^2
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 81
b = 9

Answer:

C.  9 m

Step-by-step explanation:

The Pythagorean theorem says

[tex]leg_{1} ^{2} + leg_{2} ^{2} = hyp^{2}[/tex]

Let the third side, which is a leg, = x

[tex]12^{2} + x^{2} = 15^{2}[/tex]

144 + [tex]x^{2}[/tex] = 225

[tex]x^{2} = 81\\x = \sqrt{81} = 9[/tex]

C.  9 m
