First use the pythagorean theorem to find the hypotenuse \[a^2+b^2=c^2\]
faithkristine:
ok
snowflake0531:
So using that what is the hypotenuse side's length
faithkristine:
idk how to plug that in haha ya girl dumb
i havent been able to do math since the 6th grade
ill never get it

So we have sides
16 and 30
\[16^2+30^2=x^2\] what is x^2
faithkristine:
i did 16squared + 30squared and got 1156
snowflake0531:
Yes and what is the square root of 1156
faithkristine:
34
snowflake0531:
Yes so hypotenuse is 34

So now look at x, we want sin X, so what is the opposite side, what is hypotenuse
faithkristine:
0.5592
faithkristine:
?
snowflake0531:
...what is the opposite side, what is the hypotenuse
faithkristine:
idk

snowflake0531:
Look at angle X, what is the side length of the side opposite to that
faithkristine:
im still confused just tell me
snowflake0531:
We would have the opposite side of 16, and the hypotenuse, as said, is 34
\[\sin(x) = \frac {16}{34}\]
faithkristine:
ok

So we can round it to 28.0725
agreed?
faithkristine:
yes
snowflake0531:
So that's the answer to the first one
faithkristine:
ok
snowflake0531:
One thing you should know is that with teh opposite angle and difference sin w/ cos, it's the same thing
so for the second, it's also 28.0725

faithkristine:
oh ok thanks
snowflake0531:
actually wait i did it wrong
sinx would be 16/34
And that would be 0.47058823529 which would round to 0.4706
faithkristine:
@snowflake0531 the answers are wrong
snowflake0531:
And cos x would be 30/34 which is 0.88235294117, which rounds to 0.8824
faithkristine:
the 28.0725 is wrong
