Answer:
Step-by-step explanation:
Divide everything in the equation by tan 6
![3=xtan10-1](https://tex.z-dn.net/?f=3%3Dxtan10-1)
Then add 1 to both sides
![4=xtan10](https://tex.z-dn.net/?f=4%3Dxtan10)
divide by tan 10
![x=22.69](https://tex.z-dn.net/?f=x%3D22.69)
Then plug that into ![a=xtan10](https://tex.z-dn.net/?f=a%3Dxtan10)
which is
![a=22.69tan10](https://tex.z-dn.net/?f=a%3D22.69tan10)
Simplifies to 4
