Based on the figure, which equation is true?

2 sin x° = cos y°

2 cos x° = tan y°

2 tan x° = sin y°

2 sin x° = tan y°

Have you use your trig definitions and pythagorean theorm to find the missing parts of the triangles?

anonymous · Answer

i think its the first one but im not sure

anonymous · Answer

Why do you think it's true?

directrix · Answer

This is an odd question. Triangle ADC is pictured as a right triangle with hypotenuse 10 AND a leg of 10. That cannot be as the hypotenuse of a given right triangle is the longest side of the triangle.

I do have that x = 30 degrees because sin x = 1/2 and x = 30.

anonymous · Answer

yeah i know the values its just the way the triangle is presented and i cant really use elimination in answers

I'm tryiing to figure out what "they" might have meant to write and then to attempt to find an answer based on that wrong assumption.

@Rouge --> Why 2 sin x° = tan y°   --> Just wondering?
