Given the general identity tan x =sin x/cos x , which equation relating the acute angles, a and c, of a right ∆abc is true?

a. tan a = sin a/sin c
b. cos a = tan (90-a)/sin (90-c)
c. sin c = cos a/tan c
d. cos a = tan c
e. sin c = cos (90-c)/tan a

Use the converse of the side-splitter theorem to determine if tu || rs. which statement is true? line segment tu is parallel to line segment rs because 32/36 = 40/50 line segment tu is not parallel to line segment rs because 32/36 not equal 40/50. line segment tu is parallel to line segment rs because 32/36 = 40/50. line segment tu is not parallel to line segment rs because 32/36 not equal 40/50 .
