Use the pythagorean theorem to find the missing measure

 Before answering the question let's cover over  Pythagorean Theorem. 



We would first find six squared and then we would find 8 squared and add those numbers together. 

= 36
= 64

We then add these numbers. 
 
64+36=100 

We are almost done! Now we just need to find the square root of 100. In this case, we find square root by finding a number that can be multiplied by itself which would be 10 in this scenario. 

= 100

Therefore, the square root of 100 would be 10 and the answer would also be 10. The missing measure is 10m. 

The missing measure is 10m.
