The hypotenuse of the triangle is 8.603487665. But if you’re rounding to the nearest tenth, the answer would be 8.6
Explanation: you use the square root button on the calculator and add 8.1+2.9 but make sure you square the numbers because you’re finding the hypotenuse. I attached a pic for you to see what I typed in the calculator:)
Step-by-step explanation: A is not possible because the shape and the way it is drawn is nearly the same as the figure given. The shape of B is different from the given shape. C is a little too flat to be considered symmetrical to the figure. Which leaves only option D.
