Answer: Choice C
7 divided by cosec 50 degrees
=====================================
Explanation:
Abbreviations:
sec = secant
cot = cotangent
cosec = cosecant (csc is also a widely used abbreviation)
-----------------
Let the horizontal leg be x
This leg is opposite the angle 50 degrees. The hypotenuse is 7
Opposite = x
Hypotenuse = 7
We'll either use the sine rule or the cosecant (csc) rule
sine = opposite/hypotenuse
cosecant = hypotenuse/opposite
Since "sine" is nowhere to be found in the answer choices, we'll use the cosecant rule
-----------
cosecant = hypotenuse/opposite
csc(angle) = hypotenuse/opposite
csc(50) = 7/x
x*csc(50) = 7
x = 7/csc(50)
This is why the answer is choice C
Answer:
6 tickets
Step-by-step explanation:
Amount spent by Mr Harrison on plane tickets = $3600
Cost of each ticket = $585
Thus, largest number of tickets purchased is;
n = 3600/585
n = 6.15
Approximating to the nearest whole number gives 6 tickets
