C
He payed $10.95 for 6 flowers. You want to find the price per each flower.
An equation to model this situation would be 6x = 10.95 where x = price per flower.
To solve this divide each side by 6.
10.95/6 = 1.825
Essentially to find the price per an individual thing you need to divide the total price by the amount of the item purchased.
He payed $1.825 per flower.

Step-by-step explanation:
(3)
Given cosΘ = - 
Then by Pythagoras' theorem the third side is 3 ( 3,4, 5 triangle )
Since Θ in second quadrant then sinΘ > 0
sinΘ = 
Using the trigonometric identity
sin2Θ = 2sinΘcosΘ, then
sin2Θ = 2 ×
× -
= - 
(4)
Using the trigonometric identity
cos(x - y) = cosxcosy + sinxsiny
note cos15° = cos(45 - 30)°
cos(45 - 30) = cos45cos30 + sin45sin30
= (

Answer:
1,-2
Step-by-step explanation:
You can also say the answer is C.
tan 52 = 180/a; a = 180/tan 52
tan 43 = 180/b; b = 180/tan 43
you need to calculate, a-b = 180/tan 52 - 180/tan 43
substitute the value of tan thetas, and calculate it simply...
