marysya [2.9K]

<span>For this case what you should do is write the following function:</span>

<span> y = (a / b) * 100</span>

<span> Where,</span>

<span> A: amount of successful free throws</span>

<span> B: total amount of free throws</span>

<span> Substituting values we have:</span>

<span><span> y  = (21/30) * 100</span></span>

<span><span> The result is:</span></span>

<span><span> Y = 70% (as we expected)</span></span>

<span><span> Answer:</span></span>

<span><span> a rational function that can model the player's free throw percentage is:</span></span>

List the sides of triangle WXY in order from smallest to largest.
nataly862011 [7]

Answer:

Using the relation between angles and sides of any triangle the answer is:

Third option: WX, XY, YW

Step-by-step explanation:

<X=90° (right angle)

<W=51°

<Y=?

The sum of the interior angles of any triangle is 180°, then:

<W+<X+<Y=180°

Replacing the given values:

51°+90°+<Y=180°

141°+<Y=180°

Solving for <Y: Subtracting 141° both sides of the equation:

141°+<Y-141°=180°-141°

<Y=39°

The order of the angles from smallest to largest is:

<Y=39°, <W=51°, <X=90°

The opposite sides to these angles must be ordered in the same way:

Opposite side to <Y: WX

Opposite side to <W: XY

Opposite side to <X: YW

Then the order of the sides from smallest to largest is:

WX, XY, YW
