if the explanation is good, the answer falls into place

Im not quite sure what that means? I didn't explain anything I was actually looking for an explanation on to how to solve this.

amistre64 · Answer

find the values of the answers using the definition of the trig functions

campbell_st · Answer

the upper triangle has measurements for the adjacent sideAB = 5 cm and the hypotenuse AC = 10 cm

and $$Cos = \frac{adj}{hyp} $$

 so 

$$\cos(x) = \frac{5}{10} $$


in the lower triangle

you have the opposite side AD = 10 cm and adjacent side AC = 10 cm

and 

$$\tan = \frac{opp}{adj}$$

so 

$$\tan(y) = \frac {10}{10}$$

I'll let you find the answer based on the above infromation

sin = over/hyp

.... campbell FINALLY got it out lol
