Answer:
![\large\boxed{a=\dfrac{K}{4+9b}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Ba%3D%5Cdfrac%7BK%7D%7B4%2B9b%7D%7D)
Step-by-step explanation:
![K=4a+9ab\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\K=a(4+9b)\qquad\text{divide both sides by}\ (4+9b)\neq0\\\\\dfrac{K}{(4+9b)}=\dfrac{a(4+9b)}{(4+9b)}\\\\\dfrac{K}{4+9b}=a](https://tex.z-dn.net/?f=K%3D4a%2B9ab%5Cqquad%5Ctext%7Buse%20the%20distributive%20property%7D%5C%20a%28b%2Bc%29%3Dab%2Bac%5C%5C%5C%5CK%3Da%284%2B9b%29%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%7D%5C%20%284%2B9b%29%5Cneq0%5C%5C%5C%5C%5Cdfrac%7BK%7D%7B%284%2B9b%29%7D%3D%5Cdfrac%7Ba%284%2B9b%29%7D%7B%284%2B9b%29%7D%5C%5C%5C%5C%5Cdfrac%7BK%7D%7B4%2B9b%7D%3Da)
Depends of the size of the quadrilateral in relation to the circle, but otherwise, yes
Answer: -1
Step-by-step explanation:
First change tan(315) to:
![\frac{\sin(315)}{\cos(315)}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csin%28315%29%7D%7B%5Ccos%28315%29%7D)
Then evaluate the sine and cosine function. What is the y component of 315 degrees? What is the x component of 315 degrees?
![-\frac{\sqrt{2} }{2} /\frac{\sqrt{2} }{2} =-1](https://tex.z-dn.net/?f=-%5Cfrac%7B%5Csqrt%7B2%7D%20%7D%7B2%7D%20%2F%5Cfrac%7B%5Csqrt%7B2%7D%20%7D%7B2%7D%20%3D-1)
