Answer:the first one is 16 and the second one I don’t know and it’s kinda hard to see
Answer:
∠B = 54 °
Step-by-step explanation:
If sum of two angles add up to 180°, then the two angles are called supplementary.
m∠A + m ∠B = 180°
7x + 7 + 4x - 14 = 180
7x + 4x + 7 - 14 = 180
11x - 7 = 180
11x = 180 + 7
11x = 187
x = 187 ÷ 11

m∠B = 4x - 14
= 4*17 - 14
= 68 - 14

N= the # of books
So you're trying to find n and you have the cost for the printed books, which is 15,000, so you would set up your equation like this:
15,000=500+10n
Subtract 500 from each side
14850=10n
Divide by 10
n=1,485 books are printed
