Answer:
a=1/2b, 2a=b
Step-by-step explanation:
Since angle a is 1/2 the size of angle b, a=1/2b and b=2a. In order to get a numeral answer, you need the number of one of the angles.

Answer:
![5\sqrt{2}](https://tex.z-dn.net/?f=5%5Csqrt%7B2%7D)
Step-by-step explanation:
distance between two points:
![d = \sqrt{(x_{2}-x_{1})^{2}+ (y_{2}-y_{1})^{2}}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x_%7B2%7D-x_%7B1%7D%29%5E%7B2%7D%2B%20%28y_%7B2%7D-y_%7B1%7D%29%5E%7B2%7D%7D)
we have:
(-4, -6), (3, -7)
![x_{1} = -4](https://tex.z-dn.net/?f=x_%7B1%7D%20%3D%20-4)
![y_{1} =-6](https://tex.z-dn.net/?f=y_%7B1%7D%20%3D-6)
![x_{2} = 3](https://tex.z-dn.net/?f=x_%7B2%7D%20%3D%203)
![y_{2} =-7](https://tex.z-dn.net/?f=y_%7B2%7D%20%3D-7)
so we have:
![d =\sqrt{(3-(-4))^{2}+ (-7-(-6))^{2}}\\\\d =\sqrt{(7)^{2}+ (-1)^{2}}\\\\d = \sqrt{49+ 1}\\\\d=\sqrt{50}\\\\d=5\sqrt{2}](https://tex.z-dn.net/?f=d%20%3D%5Csqrt%7B%283-%28-4%29%29%5E%7B2%7D%2B%20%28-7-%28-6%29%29%5E%7B2%7D%7D%5C%5C%5C%5Cd%20%3D%5Csqrt%7B%287%29%5E%7B2%7D%2B%20%28-1%29%5E%7B2%7D%7D%5C%5C%5C%5Cd%20%3D%20%5Csqrt%7B49%2B%201%7D%5C%5C%5C%5Cd%3D%5Csqrt%7B50%7D%5C%5C%5C%5Cd%3D5%5Csqrt%7B2%7D)
2a+4(7+5a)
Distribute 4 into 7 and 5a
2a+28+20a
Combine like terms
Final Answer: 22a+28
