Answer:

x = 6.6

Step-by-step explanation:

law of cosines:

x² = b² + c² - 2ac · cosX

x² = 5² + 8² - 2(5 · 8) · cos 55°

x² = 25 + 64 - 80· cos 55°

x² = 25 + 64 - 45.89

x² = 89 - 45.89

x² = 43.11

x = √43.11

x ≈ 6.6

A zoo has 15 emperor penguins The emperor penguins make up 30% of all the penguins at the zoo. How many penguins live at the zoo
r-ruslan [8.4K]

Let x + 15 = total penguins

15/ (x +15) = .30

15 = .30x + 4.5

.30x  = 10.5

x = 35

Total penguins = 15 + 35 = 50

Double Check

15 / 50 * 100 = 30%  Correct!!!
