Which trigonometric ratio relates base and hypotenuse??

anonymous · Answer

I know the ratio, but I need a little help in outlining steps.
The trigo ratio is a^2+b^2=c^2

He talking about sine and cos! Not Pythagoras theorem! :) @StrikeEagle

potatoes.ramu · Answer

Do you know what cos30 is?

anonymous · Answer

oh hmm okay
Cos - Adjacent/Hypotenuse
Sine - Opposite/H
Tangent - O/A

anonymous · Answer

yeah 0.5

anonymous · Answer

its easy use AAS theorem and then put values in b/sin B = c/sin C
if I am not mistaken

anonymous · Answer

Ok can you just help me solve this? I am using this question as a template to solve other questions

potatoes.ramu · Answer

$$\cos30=\sqrt{3}/2$$

potatoes.ramu · Answer

So $$\sqrt{3}/2=7/y$$

potatoes.ramu · Answer

Find y first. And then you can use Pythagoras theorem to find x! :)
