Answer:
sin(a)=3/5
cos(a)=4/5
tan(a)=3/4
Step-by-step explanation:
We know that sinФ=Opposite/Hypotenuse, cosФ=Adjacent/Hypotenuse, and tanФ=Opposite/Adjacent. We can remember this with the phrase SOH-CAH-TOA.
We know our angle is A. The opposite side of A is 3. The adjacent side of A is 4. The hypothenuse is 5.
Now, we can plug the given information into the formulas and get the solutions.
sin(a)=3/5
cos(a)=4/5
tan(a)=3/4
