Answer: 10mm
Step-by-step explanation: You are going to use the "Pythagorean Theorem" method.
Step 1 :
Equation : a^2+b^2=c^2
plug in your data to the equation given. Then simplify and add.
6^2+8^2=C^2
simplify : 36 + 64 = C^2
simplify : 100 = C^2
Step 2 :
Find what goes into 100 evenly.
100 = 10^2 = (10)(10) = C^2
Step 3:
Find the square root of 10^2 = C^2
10 = c
Last Step :
The length of the unknown leg in the right triangle is 10mm
YAY!!!! you're finished! I hope I explained this so it was easy for you to understand.
