C. -4 because you factor and add like terms
Answer:
Sorry if I am wrong, but I believe it is (-33/2,38)
-33/2 being x
38 being y
Step-by-step explanation:
Eight and five hundred, seventeen thousandths
Answer: 50
Step-by-step explanation:
Substitute 3 for x:
= 20(3)-10
= 50
y = 218.2. The lenght of side y by trigonometry is 218.2.
In order to solve this problem we are going to use the angles and sides of a right triangle and its relation by expressions that we call trigonometric ratios.
In the image we can see that the lenght of the opposite leg is 141 , we do not know the lenght of the adjacent leg y and the hypotenuse x. The key to solve this problem is to use trigonometric ratios and the equation tan θ = sin θ/cos θ = opposite leg/adyacent leg = 141/y
Clear for y for the equation tan θ = sin θ/cos θ = 141/y, we obtain:
y = arctan θ (141)
y = arctan (43°)(141) = 218.2
