Answer: 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.
