Use the sine function.

sine = opposite side of triangle divided by the hypotenuse.

Here is the set up:

sin(50°) = BC/3

sin(50°)/3 = BC

Use your calculator to simply left side.

Take it from here.

Answer:

A

Step-by-step explanation:

I will edit and add my explanation

The 3 and 2 are both positive if the information that was given in the screenshot is standalone.

So if the numerals are both positive, they must be traveling to the right because the number line is increasing towards the right.

We can narrow the choices down to A and C because they both move right.

Since neither of the numbers are negative, it must start from the center 0 and increase, so it must be A.

3 * 2 is also 6, so it must end on 6.

Two numbers are consecutive positive multiples of 3. Three
Sunny_sXe [5.5K]

Answer:

  18, 21

Step-by-step explanation:

Let x represent the smaller number. Then x+3 is the larger number, and the other relation between them is ...

  3(x+3) = (7/10)(5x)

  6x +18 = 7x . . . . . multiply by 2 and simplify

  18 = x . . . . . . . . . . subtract 6x

The two numbers are 18 and 21.

Alexa drew AB on a piece of a paper, and then folded the paper so that Point A was on Point B. She claims the crease forms right
Shkiper50 [21]
She would be right because if you look at it she folded the paper in half, so A was on top of B. And yes it does form right angle it's a lot easier to see if you do it is a little hard to explain~ Sorry

Please help!! I'll give 50 points
Scrat [10]

Answer: y=0 and x=3

Step 1: Solve for x in 2x+9y=6.

2x+9y=6

2x=6-9y (Subtract 9y from both sides)

x=3 - 4.5y( Divide both sides by 2)

Step 2: Replace x with 3-4.5y

-7x - 8y = -21\\-7(3-4.5y) - 8y = -21\\

Step 3: Solve for y

(-21)+31.5y-8y=(-21) (By looking at this, we can determine that y=0)

Step 4: Replace y with 0

2x+9y=6\\2x+9(0)=6\\2x=6\\

x=3 (Divide both sides 2)

Therefore, y=0 and x=3
