Question

If sin theta = a/b, then what is the value of cos theta?

Answer 1

Step-by-step explanation:

Sin theta = P/H = a/b

Base = √h²-p²

= √b²-a²

Cos theta = B/H

= √b²-a²/b

Answer 2

sin theta = a/b

sin theta = perpendicular/hypotenuse

p=a

h=b

cos theta = base/hypotenuse

base = square root of b^2-a^2
