Recall the Trigonometric Ratio below:

For csc, sec and cot - they are reciprocal of sin,cos and tan.

What we know now is our hypotenuse, adjacent and opposite length.
- hypotenuse = 15
- opposite = 12
- adjacent = 9
Therefore,
As for the reciprocal of three trigonometric ratio. We just swap the numerator and denominator.

Answer
- sin = 12/15 —> 4/5
- cos = 9/15 —> 3/5
- tan = 12/9 —> 4/3
- csc = 15/12 —> 5/4
- sec = 15/9 —> 5/3
- cot = 9/12 —> 3/4
The first is non-simplifed form while the second that has the arrow pointing is the simplest form.
Let me know if you have any doubts.
Answer:
-2
Step-by-step explanation:
The line in the graph has a slope of 1/2. Perpendicular means the opposite sign and the reciprocal, so it would be -2.
Answer:
$2,874.25 Canadian dollar
Step-by-step explanation:
The first thing to do here is to calculate the amount of the commission.
That would be 2.2% of €2,000
= 2.2/100 * €2,000 = €44
Now the total cost to pay = selling price + amount in commissions = €2,000 + €44 = €2,044
But we need our answer in the Canadian dollars
Mathematically;
$1 Canadian = €0.711142
$x Canadian = €2,044
x = (2,044 * 1)/0.711142
x = 2,874.25014975912
This is approximately $2,874.25 Canadian dollar
