What is the length of the unknown leg in the right triangle? 6 mm 8 mm mm mm
makkiz [27]

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.
