Inequalities are used to represent unequal expressions.
The inequality is: (c)
The given parameter is:
Represent the number of 3-point field goals with p.
So, the total number of points is:
Substitute 6 for Free
He scored no fewer than 18 points, means that:
He scored 18 or more points
So, the inequality is:
Rewrite as:
Hence, the correct option is (c)

Answer:
41°, 56°, 83°
Step-by-step explanation:
We can find the largest angle from the law of cosines:
c² = a² +b² -2ab·cos(C)
C = arccos((a² +b² -c²)/(2ab))
C = arccos((4² +5² -6²)/(2(4)(5))) = arccos(5/40) ≈ 82.8192°
Then the second-largest angle can be found the same way:
B = arccos((4² +6² -5²)/(2·4·6)) = arccos(27/48) ≈ 55.7711°
Of course the third angle is the difference between the sum of these and 180°:
A = 180° -82.8192° -55.7711° = 41.4096°
Rounded to the nearest degree, ...
the angles of the triangle are 41°, 56°, 83°.
