Atriangle has side lengths of 10 in, 16 in and 18 in. classify it as acute, obtuse, or right

  Acute

Step-by-step explanation:

18² ___ 10² + 16²

324 ___ 100 + 256

324 ___ 356

324 < 356

Since the hypotenuse squared is less than the sum of the side lengths squared, the triangle is acute.

NOTE: a greater than symbol would have resulted in an obtuse triangle and an equal sign would have resulted in a right triangle.

so if you do 13×3 you would get 39 so the answer should be 2 mph

Answer 2mph
