Answer:
23.7°
Step-by-step explanation:
To obtain the value of AB ; Use the cosine rule ;
Recall:
c² = a² + b² - 2ab Cos C
c² = 24² + 11² - 2*24*11 Cos75
c² = 576 + 121 - 528 * 0.2588190
c² = 697 - 136.656432
c² = 560.343568
c = sqrt(560.343568)
c = 23.6715
Hence, c = AB = 23.7°
N = -9
8(-7+n) = -128
Divide both sides by 8
-7 + n = -16
Add 7 to both sides
n = -9
-36.6 that would be the answer
Answer:
25 Hours
Step-by-step explanation:
First find how much $20 is in hours. It equals to 1 hour. Now times it as many times as you need, to get to $500, which is 25 in total.
