Question

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

Answer 1

D. 71.59

Explanation:

Answer 2

Let , missing value(_)=A

As, it is given that ,

`CosA=(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}}=(\pi)/(180)\\\\72 {\text{Degree}} =(72* 22)/(180 * 7)\\\\=1.2571`

So, missing value to the nearest hundredth= 1.26 Radians
