Question

if cos theta = 0.6 , show that 5sin theta - 3tan theta.

Answer 1

Answer:0

Step-by-step explanation:

Given Cos theta =0.6=(b/h)=6/10=3/5

Now we know, h^2=p^2+b^2

10^2-6^2=p^2

Therefore p=√(100-36)=8

Now sin theta =(p/h)=8/10=4/5

And Tan theta=(p/b)=8/6=4/3

Now 5 sin theta - 3 tan theta =5(4/5)-3(4/3)

=4-4=0
