Answer:

1). sin 30°=5/x

1/2=5/x

x=10

2)sin 30°=y/18

1/2=y/18

y=9°

cos 30°=x/18

√3/2=x/18

x=9√3

3) option D is correct

Val is going to plant y vegetable seeds in one garden 3y+5 vegetable seeds in another. Haw many seeds is val going to plant?
egoroff_w [7]

Answer:

4y+5 vegetable seeds.

Step-by-step explanation:

In order to find the total amount of vegetable seeds, you need to add y+3y+5.

You have to combine your like terms.

3y and y are like terms, so you add them to get 4y. 5 and 4y are not like terms, so you just write your expression as 4y+5.

Hope this helps!

(Pls help) I need help finding x!
Ray Of Light [21]

Answer:

x ≈ 46°

Step-by-step explanation:

Since the triangle is right use the sine ratio to solve for x

sinx = \frac{opposite}{hypotenuse} = \frac{10}{14}, hence

x = sin^{-1} ( \frac{10}{14} ) ≈ 46°
