X is the hypotenuse. I forgot to draw it.

your 3angle is 70

Which third angle?

the top one

Can you show how you got it?

yeah

Oh ok. So would I use Pythagorean triples to solve for x?

yeah

but one side is x and the other is 19 but you need to have data of another side

How do I do that? This is so confusing. Lol

probably the question is incorrect wait i'm checking

no the question is wrong you got to have two sides

It can't be wrong. I got it from my homework. Lol

any other info

Here are the choices:
A. 55.6
B. 55.8
C. 6.7
D. 6.5

pls wait

nope there's surely some problem

why will you mark the other side as x

did they tell you that they are equal

Hmmm..... good point lol

then also your answer is not coming i've calculated

did they tell you the area of the triangle

No, that's all it said besides the fact that it's not drawn to scale.

And to round to the nearest 10th

yeah theres something wrong wait i'm asking a frnd of mine

this has got to do with inverse sine function

Can you explain it, please?

\[\sin^{-1} (\frac{ 19 }{ x } = 20^{o}\]

hey i got it

its 55.8

you can try the options since its mcq

yeah

will you explain it to her

ok

I still don't know exactly how to solve it... Lol sorry, this stuff is confusing to me.

wait @Kailee1423 he'll explain it to you

you know
\[\sin = \frac{ Opposite }{ Hypotenuse }\]

its a ratio of opposite and hypotenuse

Yeah, but how do you know which side is opposite?

|dw:1438883342515:dw|

thats how you know

you got to consider the 20 degree angle

then your sin 20=19/x
sin 20 value is 0.34
so x=19/0.34=55.8

hey @Kailee1423 did you understand what we said

How did you get 0.34?

calculater sweety

just in a calculater try the value of sin 20

Oh ok. Why is it the sin of 20 instead of 19?

\[\sin 20 = 19/x\]\[0.342=19/x\]\[0.342x=19\]\[19/0.342=x\]

the angle is 20

because we always finf sin of an angle and not of a side

you dont sine the length only angle

yeah

now u understand

its actually 55.6

Thank you both! :) Sorry, my computer crashed.
