Answer:
C: 56,72,52
Step-by-step explanation:
we know that
An acute triangle is a triangle with three angles less than 90°
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
<u><em>Verify each case</em></u>
case A) The three measures are less than 90 degrees but the sum is not equal to 180 degrees (is not a triangle)
case B) The three measures are not less than 90 degrees
case C) The three measures represent an acute triangle ( the three measures are less than 90 degrees and the sum is equal to 180 degrees)
case D) The three measures are not less than 90 degrees. This triangle represent a right triangle

If the pool has a diameter of 32 feet, we use the formula C = pi*d to calculate the circumference
C = (32 ft)*pi, or approx. 100.53 ft. Because 32 ft has no decimal fraction part, it'd make more sense to round off 100.53 ft to 101 ft (which is the answer to the nearest unit).
