I think he bought 14 chicken wings, if I need to explain then I will.
Answer:
The answer to your question is x = 17.32; y = 8.67
Step-by-step explanation:
Process
1.- Use trigonometric functions to find x and y
a) sin Ф = ![\frac{opposite side}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%20side%7D%7Bhypotenuse%7D)
Ф = 60°
opposite side = 15
hypotenuse = ?
![hypotenuse = \frac{opposite side}{sin \alpha }](https://tex.z-dn.net/?f=hypotenuse%20%3D%20%5Cfrac%7Bopposite%20side%7D%7Bsin%20%5Calpha%20%7D)
![hypotenuse = \frac{15}{sin 60}](https://tex.z-dn.net/?f=hypotenuse%20%3D%20%5Cfrac%7B15%7D%7Bsin%2060%7D)
![hypotenuse = \frac{15}{0.87}](https://tex.z-dn.net/?f=hypotenuse%20%3D%20%5Cfrac%7B15%7D%7B0.87%7D)
hypotenuse = 17.32
b) cosФ = ![\frac{y}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7Bhypotenuse%7D)
![y = hypotenuse x cos 60](https://tex.z-dn.net/?f=y%20%3D%20hypotenuse%20x%20cos%2060)
![y = 17.32 x 0.5](https://tex.z-dn.net/?f=y%20%3D%2017.32%20x%200.5)
y = 8.67
Answer:

Answer:
Since it is vertical angles, 4x - 12 = 88.
Answer is 25
Step-by-step explanation:
88 + 12 = 100
100 / 4 = 25
