Answer:
12
Step-by-step explanation:
Use the pythagorean theorem ([tex]a^2+b^2=c^2[/tex]). A and b are the two legs of the triangle, and c is ALWAYS the hypotenuse. Plug in the values for a and c
[tex]a^2+b^2=c^2[/tex]
[tex]5^2+b^2=13^2[/tex]
[tex]25+b^2=169[/tex]
[tex]b^2=144[/tex]
[tex]b=12[/tex]
Answer:
b = 12m
Step-by-step explanation:
5^2 + b^2 = 13^2
25 + b^2 = 169 --> *subtract 25 form both sides*
b^2 = 144 --> find square root of 144*
b = 12
