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

Respuesta :

Answer:

Step-by-step explanation:

Divide everything in the equation by tan 6

[tex]3=xtan10-1[/tex]

Then add 1 to both sides

[tex]4=xtan10[/tex]

divide by tan 10

[tex]x=22.69[/tex]

Then plug that into [tex]a=xtan10[/tex]

which is

[tex]a=22.69tan10[/tex]

Simplifies to 4
