This can be solve using trigonometric function. since the
given side is the adjecent of the angle which is length of the shadow and the
unknown is the side opposite the angle, which is the height of chad.
Imagine right triangle with first leg to be the Chad length and second leg to be the Chad's shadow. Second leg has length 14.3 ft and since the straight-line distance from the top of Chad’s head to the end of the shadow creates a 23° angle with the ground, you could consider the trigonmetric function
