How do I solve a equation using Pythagorean theorem?

The answer for the pic you put would be 8.6 I think!

Step-by-step explanation:

Step 1:Draw a right triangle and then read through the problems again to determine the length of the legs and the hypotenuse.

Step 2:Use the Pythagorean Theorem (a2 + b2 = c2) to write an equation to be solved. Remember that a and b are the legs and c is the hypotenuse (the longest side or the side opposite the 90º angle).

Step 3:Simplify the equation by distributing and combining like terms as needed.

Step 4:Solve the equation. If the equation contains x2, set the equation equal to zero and solve the equation by factoring. If the equation does not contain x2, then solve the equation by getting the variables on one side and the numbers on the other side.

Step 5:Answer the question asked in the original question and make sure that the answer makes sense. Do not forget to include units in your final answer.
