Find side b if side a = 10 inches and side c = 16 inches. round to the nearest hundredth if the answer is uneven the picture shows a triangle a b c letters around it

Hopefully, you're talking about Pythagorean theorem.
a^2 + b^2 = c^2
They gave us side a and side c, so we plug in our values
10^2 + b^2 = 16^2
You solve the exponents 
100 + b^2 = 256
Subtract 100 on both sides
100 + b^2 = 256
-100            -100         

You're left with:
b^2 = 156You square root both sides
b = 12.489...
We round and get our final
b = 12.49
Good luck!

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
