Answer:
m∠B = 111º
Step-by-step explanation:
use law of cosines
c² = a² + b² - 2ab*cosC
---------------------------------
15² = 7² + 11² - 2(7)(11)cosB
225 = 49 + 121 - 154cosB
225 = 170 - 154cosB
Subtract 170 form both sides
55 = -154cosB
Divide both sides by -154
-0.3571428571 = cosB
m∠B = arccos -0.3571428571
use calculator
m∠B = 110.924832425009406
Rounded
m∠B = 111º

Answer:
$75.6
Explanation:
If the original cost was $70 and it was marked up 20%, the price after this is calculated as:
$70 + $70(0.2) = $70 + $14 = $84
Where $70(0.2) = $14 is the amount added to the original when it is marked up 20%.
Then, it was discounted 10%, we get that the selling price is
$84 - $84(0.1) = $84 - $8.4 = $75.6
Where $84(0.1) = $8.4 is the discount made on the initial price.
Therefore, the answer is $75.6
