Answer:
A
Step-by-step explanation:
We are given:

Since cosine is the ratio of the adjacent side over the hypotenuse, this means that the opposite side is (we can ignore negatives for now):

So, the opposite side is 5, the adjacent side is 12, and the hypotenuse is 13.
And since θ is in QIII, sine/cosecant is negative, cosine/secant is negative, and tangent/cotangent is positive.
Cosecant is given by the hypotenuse over the opposite side. Thus:

Since θ is in QIII, cosecant must be negative:

Our answer is A.
Answer:
The markup amount on the cost 39.99 $ will be: 8.78 $
Step-by-step explanation:
Given
- The cost = 39.99 (Let say in $)
As
22% = 0.22
The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22
so
Markup amount = 0.22 × 39.99
= 8.78 $
Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $
Answer:
D.
m²
Step-by-step explanation:
Area of the sector = ½*r²∅
Where,
Radius (r) = 15 m
Angle in radians (∅) = 
Plug in the values into the equation
Area of sector = 
Area of sector = 
Area of sector = 
Area of sector = 
Simplify
Area of sector =
