Question

Find the missing value to the nearest hundredth. cos_= 6/19

Answer 1

Let , missing value(_)=A

As, it is given that ,

$CosA=\frac{6}{19}\\\\ Cos A=0.3158\\\\ A=72 {\text{Degree}}$

To convert the value of A into Radians,

360°=2 π Radians

$1 {\text{degree}}=\frac{\pi}{180}\\\\72 {\text{Degree}} =\frac{72\times 22}{180 \times 7}\\\\=1.2571$

So, missing value to the nearest hundredth= 1.26 Radians
