Solve the triangle.<br><br> a = 10, b = 23, C = 95°
gayaneshka [121]
C² = a² + b² - (2ab * cosC) 
<span>c² = 10² + 23² - (2 * 10 * 23 * cos95) </span>
<span>c² = 100 + 529 - (460 * -.08715) </span>
<span>c² = 629 - (-40.1) </span>
<span>c² = 669.1 </span>
<span>c = 25.87 </span>

<span>(Sin C) / C = (Sin A) / A </span>
<span>(Sin 95) / 25.87 = SinA / 10, Remember 0 < A < 85 </span>
<span>(10 * Sin95) / 25.87 = Sin A </span>
<span>A = arcsin ((10 * sin95) / 25.87) </span>
<span>A = 22.65º </span>

<span>B = 180 - A - C </span>
<span>B = 180 - 95 - 22.65 </span>
<span>B = 62.35º </span>

<span>I hope this helps. Have a good day.</span>

After 50 soccer games, the ratio of wins to losses is 3:7. How many games did the team win? Explain how you found your answer
zalisa [80]

Answer:The team won 15 games


Step-by-step explanation:

Given no of soccer games =50

Ratio of wins to losses =3:7

Let no of wins =3x

and no of losses =7x

Now

3x+7x=50

10x=50

Dividing both sides by 10

x=5

So no of wins =3x =3\times5

=15

We found  the answer as 10 parts equals 50

So 3 parts equals 15
