Find the value of $7sin 30° cos 60°$.
Given :
The given term is 7 sin 30° cos 60°.
To do :
We have to find the value of the given term.
Solution :
We know that,
sin 30° $= \frac{1}{2}$
cos 60° $=\frac{1}{2}$
Therefore,
7 sin 30° cos 60° $= 7 \times \frac{1}{2} \times \frac{1}{2} $
$= \frac{7}{4}=1.75$
Therefore the value of 7 sin 30° cos 60° is 1.75.
