Find the values of the trigonometric functions of from the

?Find the values of the trigonometric functions of ? from the information given. tan ? = ? 20/21 and cos ?>0

tan = -20/21 , cos > 0

cosine function is positive and tangent function is negative in Quadrant IV

tan = opposite side / adjacent side = -20/21

==> hypotenuse = [20² + 21²] = 841

==> hypotenuse = 29

sin = opposite side / hypotenuse and sine function is negative in IV quadrant

==> sin = -20/29

cos = adjacent side / hypotenuse and cosine function is positive in IV quadrant

==> cos = 21/29

==> csc = 1/(sin ) = 1/(-20/29) = -29/20

==> sec = 1/(cos ) = 1/(21/29) = 29/21

==> cot = 1/(tan ) = 1/(-20/21) = -21/20
