Find the sine, cosine and tangent ratios

1)  

sinA=5/13       sinB=12/13

cosA= 12/13   cosB=5/13

tgA=5/12      tgB=12/5

2)

sinA=8/17       sinB=15/17

cosA= 15/17   cosB=8/17

tgA=8/15      tgB=15/8

3)

sinA=7/25       sinB=24/25

cosA= 24/25   cosB=7/25

tgA=7/24      tgB=24/7

4)

sinA=1/2       sinB=√3 /2

cosA= √3 /2   cosB=1/2

tgA=1/√3       tgB=√3  

5)

sinA=1/√2       sinB=1/√2

cosA= 1/√2   cosB=1/√2

tgA=1       tgB=1

a.) is the correct answer.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
