Question

What is the value of sin(t) if Cos(t)=4/5 and t is in quadrant 1

Answer 1

Answer:

0.6 or 3/5

Step-by-step explanation:

If cos(t) = 4/5, then, taking the arccos of both sides, t ≈ 36.86989765. Taking the sin of that gives you 0.6, or 3/5 in fraction form.

Answer 2

3.5 is the answer for sure
