Answer 1

@eliassaab

Answer 2

Which trigonometric ratio relates base and hypotenuse??

Answer 3

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

Answer 4

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

Answer 5

Do you know what cos30 is?

Answer 6

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

Answer 7

yeah 0.5

Answer 8

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

Answer 9

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

Answer 10

\[\cos30=\sqrt{3}/2\]

Answer 11

So \[\sqrt{3}/2=7/y\]

Answer 12

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