Question

IF SIN X = SIN 60 Cos 30 - COS 60
30, THE VALUE OF X IS / SIN X = SIN 60 cos
30 - COS 60 SIN 30
LAST X Value​

Answer 1

Answer:

X = 30.

Step-by-step explanation:

sin X = Sin 60 Cos 30 - Cos 60 Sin 30

apply ⇔ Sin(a-b) = Sin a Cos b - Cos a Sin b

Here ∵ a = 60 and b = 30

so X = a-b

X = 60 - 30.

X = 30.
