Find the length of the hypotenuse of the triangle. a) 5.36 b) 6.22 c) 9 d) 6.4

To solve this you would use the Pythagran Theorem, a^2+b^2=c^2. I counted the square units on the graph to find the length of the legs, 4 and 5. Then, I plugged them into the equation to get 16+25=c^2, which is 40=c^2=

and if you type sqrt40 into a calculator you get about 6.4. So the answer would be D.
