Simplifying tan(x + -90) = -1cotx Reorder the terms: ant(-90 + x) = -1cotx (-90 * ant + x * ant) = -1cotx (-90ant + antx) = -1cotx Solving -90ant + antx = -1cotx Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Combine like terms: -1cotx + cotx = 0 -90ant + antx + cotx = 0 Factor out the Greatest Common Factor (GCF), 't'. t(-90an + anx + cox) = 0Subproblem 1
Set the factor 't' equal to zero and attempt to solve: Simplifying t = 0 Solving t = 0 Move all terms containing a to the left, all other terms to the right. Add '-1t' to each side of the equation. t + -1t = 0 + -1t Remove the zero: 0 = -1t Simplifying 0 = -1t The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(-90an + anx + cox)' equal to zero and attempt to solve: Simplifying -90an + anx + cox = 0 Solving -90an + anx + cox = 0 Move all terms containing a to the left, all other terms to the right. Add '-1cox' to each side of the equation. -90an + anx + cox + -1cox = 0 + -1cox Combine like terms: cox + -1cox = 0 -90an + anx + 0 = 0 + -1cox -90an + anx = 0 + -1cox Remove the zero: -90an + anx = -1cox The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
