Answer:
<h2>D.</h2>
Step-by-step explanation:
The choices to this question are
a.) 1/tan(90-A)
b.) 1/sin A
c.) 1/cos(90-A)
d.) 1/tan A
We know that
, which is a trigonometric identity.
If 
then,
But, 
and 
So,
Which is the inverse of tangent, so
Therefore, the right answer is D.
An equation is formed when two equal expressions. Ms. Kilicoglu will buy 20 volleyballs and 25 basketballs.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let x be the number of volleyballs and y be the number of basketballs. Therefore, the total number of balls can be written as,
x + y = 45
x = 45 - y
Each volleyball costs $8 and each basketball costs $11. Also, Ms. Kilicoglu has only $435, therefore,
8x + 11y = 435
8(45 - y) + 11y = 435
360 - 8y + 11y = 435
3y = 75
y = 25
Substitute the value of y in the first equation,
x + y = 45
x + 25 = 45
x = 20
Hence, Ms. Kilicoglu will buy 20 volleyballs and 25 basketballs.
