Answer:
m<B = 28°
Step-by-step explanation:
Given:
m<A = 112°
m<C = 40°
AC = 14
Required:
Find, m<B, AB and BC.
SOLUTION:
✍️m<B = 180° - (112° + 40°) (sum of ∆)
m<B = 28°
✍️Using sine rule, find AB.
![\frac{AB}{sin(C)} = \frac{AC}{sin(B)}](https://tex.z-dn.net/?f=%20%5Cfrac%7BAB%7D%7Bsin%28C%29%7D%20%3D%20%5Cfrac%7BAC%7D%7Bsin%28B%29%7D%20)
Plug in the values into the equation.
![\frac{AB}{sin(40)} = \frac{14}{sin(28)}](https://tex.z-dn.net/?f=%20%5Cfrac%7BAB%7D%7Bsin%2840%29%7D%20%3D%20%5Cfrac%7B14%7D%7Bsin%2828%29%7D%20)
Cross multiply
![AB*sin(28) = 14*sin(40)](https://tex.z-dn.net/?f=%20AB%2Asin%2828%29%20%3D%2014%2Asin%2840%29%20)
Divide both sides by sin(28)
![AB = \frac{14*sin(40)}{sin(28)}](https://tex.z-dn.net/?f=%20AB%20%3D%20%5Cfrac%7B14%2Asin%2840%29%7D%7Bsin%2828%29%7D%20)
(nearest tenth)
✍️Using sine rule, find BC.
![\frac{BC}{sin(A)} = \frac{AC}{sin(B)}](https://tex.z-dn.net/?f=%20%5Cfrac%7BBC%7D%7Bsin%28A%29%7D%20%3D%20%5Cfrac%7BAC%7D%7Bsin%28B%29%7D%20)
Plug in the values into the equation.
![\frac{BC}{sin(112)} = \frac{14}{sin(28)}](https://tex.z-dn.net/?f=%20%5Cfrac%7BBC%7D%7Bsin%28112%29%7D%20%3D%20%5Cfrac%7B14%7D%7Bsin%2828%29%7D%20)
Cross multiply
![AC*sin(28) = 14*sin(112)](https://tex.z-dn.net/?f=%20AC%2Asin%2828%29%20%3D%2014%2Asin%28112%29%20)
Divide both sides by sin(28)
![AC = \frac{14*sin(112)}{sin(28)}](https://tex.z-dn.net/?f=%20AC%20%3D%20%5Cfrac%7B14%2Asin%28112%29%7D%7Bsin%2828%29%7D%20)
