Question

Please help me iffffffffffffffff

Answer 1

Answer:

10

Step-by-step explanation:

The pythagorean theorem states that a^2+b^2=c^2.  a and b are the shorter sides and c is the hypotenuse, or the longest side.  You can tell the hypotenuse because it is opposite to the right angle.

Therefore, a=6, b=8 and c=x.  You can switch a and b if you like, it doesn't really matter.

using the pythagorean thm. 6^2+8^2=x^2.  You simplify the exponents and combine like terms to get x^2=100.  You take the square root of both sides and get 10.

Answer 2

Answer:

x=10

Step-by-step explanation:

6^2+8^2=x^2

36+64=x^2

100=x^2

x=10
