Question

Based on the figure, which equation is true?
A) 2 cos x° = tan y°
B) 2 sin x° = tan y°
C)2 sin x° = cos y°
D)2 tan x° = sin y°

Answer 1

tan(y) = opp/adj

tan(y) = 10/10

tan(y) = 1

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

sin(x) = opp/hyp

sin(x) = 5/10

sin(x) = 1/2


Now compare tan(y) and sin(x). Notice that the second is half of the first. Or put another way, the first is double the second.


So 2*sin(x) = tan(y)

Answer 2

Thank you so much!!!
