This problem requires the use of trig.  Are you familiar with the three basic trig functions:  sine, cosine and tangent?

anonymous · Answer

yes. I remember them using sohcahtoa

mathmale · Answer

I assume you're supposed to solve for the angle y.

Which of the 3 trig functions involves the hypotenuse and the adjacent side (the side next to the angle in question)?

anonymous · Answer

cosine

mathmale · Answer

type out the cosine function, please.

anonymous · Answer

I forgot it..

mathmale · Answer

Please look it up on the 'net or in your textbook.

just type "cosine function" into the search bar.

anonymous · Answer

I cant find it

mathmale · Answer

See "Right-angled triangle definitions" in https://en.wikipedia.org/wiki/Trigonometric_functions

anonymous · Answer

ohh, okay. I saw it.

mathmale · Answer

type out the cosine function definition, please, using the words "hyp.," "adj."

anonymous · Answer

The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse: so called because it is the sine of the complementary or co-angle\cos A = adjacent over hypotenuse

mathmale · Answer

Great.  The cos of angle y would be the length of the adj. side over the length of the hyp.

could y ou write that out, please, in the Draw utility?|dw:1457921648659:dw|
