ANSWER:
1. cos theta= 4/5
2. tan theta = 3/4
EXPLANATION:
sin theta= 3/5
cos theta = √1-sin² theta
cos theta= √ 1-(3/5)²
cos theta= √ 1-9/25
cos theta= √ 25 -9/25
cos theta = √ 16/25
cos theta = 4/5.............ans (1)
tan theta= sin theta/cos theta
tan theta= 3/5/4/5
tan theta= 3/4 ..............ans (2)
