Whats the question?

OpenStudy (anonymous):

write the ratio and solve for x I guess

OpenStudy (anonymous):

im stuck trying to find x

Directrix (directrix):

@monica10 I was working with you before and we were interrupted. cos (63 degrees) = 23/x

Directrix (directrix):

That is the equation to be solved. The cosine of the acute angle of a right triangle is equal to the ratio of the adjacent leg length to the hypotenuse length.

Directrix (directrix):

@monica10 Does that make sense? Question?

OpenStudy (anonymous):

kinda sorta

Directrix (directrix):

If you want to review, attached is a chart of right triangle trig ratio definitions.

OpenStudy (anonymous):

this is sorta what Im learning in Pre- Calc

Directrix (directrix):

>>kinda sorta I'm guessing that this comes from being unsure about opposite and adjacent sides.

OpenStudy (anonymous):

corect

Directrix (directrix):

@monica10 Ignore intruders. The adjacent and opposite sides change a bit depending on which angle and trig function you are working with. But, you have to know which is which, opposite vs. adjacent. You also have to learn the trig ratios.

Directrix (directrix):

Locate hypotenuse first. It is the side opposite the right angle and is the longest side of a right triangle. |dw:1421803236087:dw|
