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>
From the side I think it is (2 x 2269.5 - 6) cm and at the bottom it is (4530 + 3) cm. Both of them are equal to 4533 cm.
Answer:
x=3
y=6
Step-by-step explanation:
y= x+3
5x-9 = x+3
4x= 12
x= 3
Y =6
Your pic don't have the answer.
But I can tell you the correct points are : (0, 3) (-1 1/2, 0)
