If c is the longest side and a and b are the shorter sides, then the triangle is acute if
.
The longest side is 20, the shorter sides are x and x+4.
The zeros are -16 and 12, the coefficient of x² is positive so the parabola opens upwards. The values greater than zero are in the interval
.
The sides of the triangle must be positive numbers, so
.
There's one number that satisfies this inequality: 14.
The answer is D.
