so for a tangent and a secant, you multiply x^2 (since it’s a tangent you square it) and test that equal to 6(6+12) so now you have x^2=6(6+12). solve for X to get sqrt(108) or 10.4
the equation is — tan^2=outside x whole thing
remember to ADD the entire secant (so add 6 plus 12) don’t multiply them (6x12)
x^2=6(6+12)
x^2=6(18) OR x^2=36+72
x^2=108
x=sqrt(108) OR x=10.4
