If sine of x equals 1 over 2, what is cos(x) and tan(x)? explain your steps in complete sentences.

Sin Θ = opposite / hypotenuse
cos Θ = adjacent / hypotenuse
tan Θ = opposite / adjacent

sin x = 1/2  ⇒⇒ opposite is 1 ; hypotenuse is 2
cos x = ? / 2 ⇒ ? = √3 value of adjacent
tan x = 1 / ?

This is the 30 - 60 - 90 triangle.

sin 30 = 0.50
cos 30 = 0.866
tan 30 = 0.577

60 ÷ -20 x makes x = -3
