Question

Dose any one know what to do

Answer 1

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

Answer 2

Answer:

Step-by-step explanation

pythagorean theory

10^2+7.5^2=c^2

156.25=c^2

$\sqrt{156.25}$=$\sqrt{c^2}$

12.5=c
