Question

Write the function in terms of the cofnction with an acute angle.
tan 18degrees
A. sec18deg
B. cot18deg
C. cot72deg
D. cot108deg
find a solution for the equation.
sin(2theta+20deg) = cos(3theta-5deg)
thnkks:))

bobpursley · Answer

draw a right triangle. Let A and B be the acute angles. Isn't tanA=ctnB, so tanA=ctn(90-A)
