How do you find a missing side on a right angled triangle when given two sides?
Please help 
+130466 It depends upon which side you're missing
If it's the hypoteneuse (the side opposite the right angle), we just square each of the other two known sides, add these together, and then take the square root of this sum....that's the hypoteneuse
If it's any other side, we square both of the other two known sides, and subtract the smaller square from the larger, and take the square root of that difference. That's the length of the missing side (called a "leg").
