Question

Use the division property of equality to solve for x in the equation in number 12

Number 12:
3 tan 6 = x tan 10 – x tan 6
3 tan 6 = x(tan 10 – tan 6)

Substitute the value of x into the equation in number 7 and solve for a

Number 7:
Tan 10 = a/x → x tan 10 = a/x * x → a = x tan 10

Answer 1

Explanation:

Divide everything in the equation by tan 6

`3=xtan10-1`

Then add 1 to both sides

`4=xtan10`

divide by tan 10

`x=22.69`

Then plug that into
`a=xtan10`

which is

`a=22.69tan10`
