Question

if cos =0.6,find the value of 5sin-3tan​

Answer 1

Answer:

Answer is 0

Step-by-step explanation:

Tan = sin/cos.

So, we get 0 as result.

5 sin - 3 * sin/cos

Cos =6/10

5 sin - 3* sin/6/10

5sin - 5 sin

=0

Answer 2

Step-by-step explanation:

5sin-3tan. (sin)2 + (cos)2= 1.

(0.6)2 +sin2 = 1

0.36 + sin2 = 1

sin2 = 1-0.36

sin2= 0.64

taking square root on both sides,we get

sin = 0.8

tan = sin/cos

tan = 0.8/o.6

tan = 1.33333333

=5(0.8)-3(1.33)

=4-3.99

=0.01
