ANSWER
(D)54.1°
EXPLANATION
The measure of angle P can be calculated using the cosine ratio.
We know the adjacent side to angle P to be 33.8 and the hypotenuse of the right triangle is 57.6 units.
Take cosine inverse,
To the nearest tenth, the measure of <P is 54.1°
We assume w is the number of <em>inches</em> of width (as opposed to <em>feet</em> or some other measure). The length is 7 inches more than the width, so is w+7. The area is the product of these dimensions, and the problem statement tells us that area is greater than 375 in².
... w(w+7) > 375 . . . . . the inequality that can be used to find dimensions
Substitute 3 into the expression for c and -4 for d. So, 2c/d = 2(3)/(-4) = 6/-4 = -3/2. The answer is -3/2.
