Answer:
![AB = 11.3](https://tex.z-dn.net/?f=AB%20%3D%2011.3)
Step-by-step explanation:
Given
The attached triangle
Required
Length AB
To do this, we make use of sine law which is represented as:
![\frac{a}{\sin(a)} = \frac{b}{\sin(b)} = \frac{c}{\sin(c)}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B%5Csin%28a%29%7D%20%3D%20%5Cfrac%7Bb%7D%7B%5Csin%28b%29%7D%20%3D%20%5Cfrac%7Bc%7D%7B%5Csin%28c%29%7D)
So, we have:
![\frac{15}{\sin(70)} = \frac{AB}{\sin(45)}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B%5Csin%2870%29%7D%20%3D%20%5Cfrac%7BAB%7D%7B%5Csin%2845%29%7D)
Make AB the subject
![AB = \frac{15}{\sin(70)} * \sin(45)](https://tex.z-dn.net/?f=AB%20%3D%20%5Cfrac%7B15%7D%7B%5Csin%2870%29%7D%20%2A%20%5Csin%2845%29)
![AB = \frac{15}{0.9397} *0.7071](https://tex.z-dn.net/?f=AB%20%3D%20%5Cfrac%7B15%7D%7B0.9397%7D%20%2A0.7071)
![AB = 11.3](https://tex.z-dn.net/?f=AB%20%3D%2011.3)
I believe (a+b)^5 would be the answer
