Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles. B = 46°, a = 12, b = 11
andreyandreev [35.5K]
*Hint: The Law of Sines is Sin A/a = Sin B/b = Sin C/c

In order to solve this equation, you will have to use this equation:

A= sin^(-1)[a sinB/b]
A= sin^ (-1) [12 (sin 46°) / 11]
A = sin^ (-1) [8.632077604/11]
A = sin ^(-1) [0.7847343276]
A = 51.69611349

Therefore, Sine A would be about 52°

Find the selling price. Explain how you solved the question. I might mark you as brainliest!

Wow !  Now THERE's an incentive !  I'm just glad I got in
early enough so that there's an answer block left open.

If you should happen to glance at these three problems,
you'll notice that they're all the same problem, just with
different numbers.  So if somebody showed you how to do
ONE of them, you'd know how to do ALL of them.

1).  Markup = 10% of $50 = 0.1 x $50 = $5
       Selling price = ($50 + $5)  =  $55 .

2).  Markup = 60% of $80 = 0.6 x $80 = $48
      Selling price = ($80 + $48)  =  $128 .
    
3).  Markup = 25% of $140 = 0.25 x $140 = $35
      Selling price = ($140 + $35)  =  $175 .
