Answer:
Step-by-step explanation:
Let 
represent the cost of the torch and 
represent the cost of the battery.
The torch and a battery cost £2.50 altogether.
The torch costs £2.00 more than the battery.
We substitute the second equation into the first equation to get;
£2.50
The price of the battery is £0.25
We express this as a fraction of the total cost which is £2.50 to get;

Step-by-step explanation:
:)
I believe it is c but im not positive
The answer is two in this situation
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>
