Question

6.
If 5 cot0 = 4, then the value of (2 sin 0 - 5cos 0) ÷ sin 0 is
(a) -2
(b) 2
(c) 6
(d) -6​

Answer 1

Answer:

_2

Step-by-step explanation:

Cot0=4/5

We know cot0= cos0/sin0

Since, cos0=4, sin0=5

Therefore, (2 sin0 _5cos0) /sin0

=2.5_5.4/5

=10_20 /5

=_2

Answer 2

Answer:

a) -2

Step-by-step explanation:

5Cot0=4

Cot0 = 4/5

Cos 0

----------- = Cot0=4/5

Sin0

Cos0=4

Sin0= 5

2sin0-5cos0. 2*5-5*4

-------------------- = -----------

Sin0. 5

10-20

= -----------= -10/5 = -2
