Answer:
Reverse the x and y:
x = 3y + 4.
Now subtract 4 from both sides:
x - 4 = 3y
Divide both sides by 3:
1/3 x - 4/3 = y
A. 38 degrees
B. 38 degrees
C. 142 degrees
We know 350 = 5t^2 + 10
So 5t^2 = 340
t^2 = 68
Take the square root of both sides to get t = 8.246 years.
Answer:
The perimeter of triangle is 30ft.
Step-by-step explanation:
First you have to find the value of a using Pythogoras Theorem, a² + b² = c² where a and b is the sides and c is the hypotenuse :
![{a}^{2} + {b}^{2} = {c}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Bb%7D%5E%7B2%7D%20%3D%20%20%20%7Bc%7D%5E%7B2%7D%20)
![{a}^{2} = {c}^{2} - {b}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%3D%20%20%7Bc%7D%5E%7B2%7D%20%20-%20%20%7Bb%7D%5E%7B2%7D%20)
![a = \sqrt{ {c}^{2} - {b}^{2} }](https://tex.z-dn.net/?f=a%20%3D%20%20%5Csqrt%7B%20%7Bc%7D%5E%7B2%7D%20-%20%20%7Bb%7D%5E%7B2%7D%20%20%7D%20)
Let b = 12,
Let c = 13,
![a = \sqrt{ {13}^{2} - 12 {?}^{2} }](https://tex.z-dn.net/?f=a%20%3D%20%20%5Csqrt%7B%20%7B13%7D%5E%7B2%7D%20-%2012%20%7B%3F%7D%5E%7B2%7D%20%20%7D%20)
![a = \sqrt{25}](https://tex.z-dn.net/?f=a%20%3D%20%20%5Csqrt%7B25%7D%20)
![a = 5feet](https://tex.z-dn.net/?f=a%20%3D%205feet)
Next you have to find the perimeter of triangle by adding all the sides together :
![perimeter = 5 + 12 + 13](https://tex.z-dn.net/?f=perimeter%20%3D%205%20%2B%2012%20%2B%2013)
![perimeter = 30feet](https://tex.z-dn.net/?f=perimeter%20%3D%2030feet)
