Question

The exact value of $\frac{96\sin {80}^0\sin {65}^0\sin {35}^0}{\sin {20}^0+\sin {50}^0+\sin {110}^0}$ is equals to:

• A. $2.90$
• B. $2.30$
• C. $2.40$
• D. $2.10$

Answer 1

Answer: (C)

$2.40$

$\frac{96\sin {80}^0\sin {65}^0\sin {35}^0}{\sin {20}^0+\sin {50}^0+\sin {110}^0}$

$\Rightarrow \frac{96\times 0.98\times 0.91\times 0.57}{0.34+0.77+0.94}$

$\Rightarrow 2.40$

Hence, the answer is $\mathrm{2.40.}$
