Answer:
40/41
Step-by-step explanation:
tanB=opposite length/adjacent length
tanB=40/41
*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°
the answer: b=9 hope this helps!
Answer:
A
Step-by-step explanation:
-5/6 x 2 pretty much. 2 and 6 cross cancel, making the answer -5/3
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 .
