If the sin of angle x is 4 over 5 and the triangle was dilated to be two times as big as the original, what would be the value of the sin of x for the dilated triangle?

@iGreen @Adrian93334 @guitarplayer @jigglypuff314 please help me with this question:(

I got 4/5 because i dont think an angle changes when its dilated?

jigglypuff314 · Answer

angles don't change in size when you dialate a figure
that is correct :)

anonymous · Answer

yeah......!!! The value of sin is the same for similar triangles...size doesn't matter

Find the sine ratio of angle Θ

anonymous · Answer

would it be 15/17?

jigglypuff314 · Answer

please ask separate questions as different posts next time please :)
but for this one, sin(angle) = (opposite side)/(hypotenuse) 
so yes, 15/17 is correct :)

anonymous · Answer

because I know sine is opposite / Hypot.

anonymous · Answer

wait...isnt that for side? How can i find the angles?

jigglypuff314 · Answer

mmm I think 15/17 is correct because it is asking for a ratio

oh okay, thank you:)
