In the right triangle shown, m\angle V = 60\degreem∠V=60°m, angle, V, equals, 60, degree and UV= 18UV=18U, V, equals, 18.

How long is UWUWU, W?

Step-by-step explanation:

Given

θ = m∠B = 60⁰

BC =

So we have to determine the length of AB which is Hypotenuse.

i.e. AB = Hypotenuse = x ?

so

Using the formula

Cos θ = Adjacent / Hypotenuse

Here:

Adjacent = BC =

so

Cos θ = Adjacent / Hypotenuse

           ∵ AB = Hypotenuse = x

         ∵

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

24/56=hx^7
