Sine and cosine has period of 2π and tangent has period of π
So basically same question as sin(0), cos(0), and tan(0)
sin(0) = 0
cos(0) = 1
tan(0) = sin(0) / cos(0) = 0 / 1 = 0
So final answers are sin(360°) = 0, cos(360°) = 1, tan(360°) = 0
Answer:
28
Step-by-step explanation:
Cross multiply
18k = 12 x 42
18 k = 504
k = 504/18
k = 28
