Question

If cos theta=4/5 then find the value of 2costheta-sin theta/cot theta -tan theta

Answer 1

Answer:

12/7

Step-by-step explanation:

cos theta is b/h so b=4 and h is 5.

find p by Pythagoras = 3

2 cos theta - sin theta / cot theta- tan theta

=(2×4/5-3/5)/(4/3-3/4)

=(8-3/5)/(16-9/12)

=(1)/(7/12)

= 12 /7
