In ΔXYZ, ∠Y is a right angle and sin X = 12/25 Find sec X, tan X, and cos Z in fraction and in decimal form. Round to the neares

Bezzdna [24]

Answer:

∠Y is a right angle
∠X and ∠Z are complementary angles
sin X = 12/25

-------------

sec X = 1/cos X = $1/\sqrt{1- sin^2X} = 1/\sqrt{1 - 12^2/25^2} = 1/\sqrt{481}/25 = 25/\sqrt{481}$
tan X = sin X / cos X = $12/{25 : {\sqrt{481} }/25 = 12/{\sqrt{481} }$
cos Z = sin X = 12/25
