Answer:
Below in bold.
Step-by-step explanation:
b.
If we drop a perpendicular line from B to AC and mark the point D on AC, we have 2 right triangles, with AD = DC = 16 cm.
So tan O = BD/16 = 15/8
BD = (16*15)/8
= 2*15
= 30.
So the area of triangle ABC = 16*30
= 480 cm^2.

![x=22](https://tex.z-dn.net/?f=x%3D22)
Step-by-step explanation:
![2(x-10)=24](https://tex.z-dn.net/?f=2%28x-10%29%3D24)
Distribute the parenthesis
![2x-20=24](https://tex.z-dn.net/?f=2x-20%3D24)
Add 20 to both sides
![2x=44](https://tex.z-dn.net/?f=2x%3D44)
Divide both sides by 2
![\frac{2x}{2} =\frac{44}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%20%3D%5Cfrac%7B44%7D%7B2%7D)
