Question

sin theta = 3/5 , evaluate cos theta - 1/tan theta / 2 cot theta ​

Answer 1

Sin theta =3/5 = opp/hypotenuse

By pythagoras theorem

3^2+x^2=5^2

9+x^2=25

X^2=25-9=16

X^2=16

X=4

Cos theta=adj/hypotenuse= 4/5

1/tan theta= cot theta

Cot theta = adj/opp=4/3

(4/5-4/3)/2×4/3

(12-20/15)/(8/3)

(-8/15)/(8/3)

=-1/5

The answer -1/5
