State if the three sides lengths form a right triangle. 8.4 yd, 13.5 yd, 15.9 yd
No
oYes

Yes

Step-by-step explanation:

You can use the Pythagorean Theorm to find out of the three sides form a right angle. The Longest side is the Hypotenuse, and the two Smaller sides are the Legs of the triangle.

a² + b² = c²

15.9yd would be the hypotenuse since it's the longest side.

8.4² + 13.5² = 15.9²

70.56 + 182.25 = 252.81

252.81yd = 252.81yd

Since the two legs are equal to the hypotenuse, the lengths do form a right angle.
