If cos theta = -4/7 what are the values of sin theta and tan theta?

          cosθ = ⁻⁴/₇
cos⁻¹(cosθ) = cos⁻¹(⁻⁴/₇)
                θ = 124.8499046

sinθ = sin(124.8499046) = 0.820651806
tanθ = tan(124.8499046) = -1.436140661

If jon had $4.00 then takes away $2.25, then he should have $1.75 left. $4.00 - $2.25 = $1.75 hope this ; )

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats
