Dose any one know what to do

Answer:
Step-by-step explanation
pythagorean theory
10^2+7.5^2=c^2
156.25=c^2
[tex]\sqrt{156.25}[/tex]=[tex]\sqrt{c^2}[/tex]
12.5=c
Answer:
c=12.5
Step-by-step explanation:
Yes, actually I do! I love the pythagorean theorem!
So the equation for the therom is a²+b²=c²
So-
10²+7.5²=c²
(10×10)+(7.5×7.5)=c²
100+56.25=c²
156.25=c² Now we have to square root 156.25 (find the closest number that can multiply itself to make 156.25)
√156.25=12.5
c=12.5
