Answer:
Step-by-step explanation: (Don't read this if you are taking a test, please! I don't want you to get in trouble!)
The formula to find a hypotenuse is a^2 + b^2 = c^2 (a squared plus b squared = c squared).
The hypotenuse is the diagonal leg (line WH).
The line WJ = 7, and the line JH = 6. Let's make line WJ a, and line JH b.
7^2 + 6^2 = c^2. When you square a number, you multiply that number by itself. 7x7 + 6x6 = c^2. 7x7 = 49 and 6x6 = 36. Now you have 49 + 36 = c^2
49 + 36 = 85. 85 = c^2. Square root both sides. The square root of 85 = the square root of c^2 (c). c = 9.21954446. If you have to round the hypotenuse to the nearest hundredth, then your answer is 9.22. The answer for the length of the hypotenuse is 9.22
I hope this helps, but please don't use this on a test!
