The answer is A.) 9c>75+0.5c
The expenses for this equation are 75 and 0.5, so they have to be combined. And the amount she charges is on the other end.
And also the profit needs to be greater than the expense to that's why its 9c is GREATER than 75+0.5c.
B A C
The longest angle is opposite to the longest side in a triangle. The same goes for the shortest and middle angles.
B is opposite to the 57 degree angle, the shortest angle, so it’s the shortest side. A is opposite to the 59 degree angle, so it is the second shortest side. C is opposite to the 64 degree angle, the largest angle, so it’s the longest side.
For this case we have the following trigonometric relationship:
cos (y) = 8/13
Clearing the value of and we have:
y = Acos (8/13)
Calculating the angle we have:
y = 52.02012756 degrees
Rounding off we have:
y = 52.02 degrees
Answer:
the measure of angle and is:
y = 52.02 degrees
