Question

Find the trigonometric value.tan 49 degrees 20'Round to three decimal places as needed.)

Answer 1

We want to calculate tan 49°20'

First, we convert 20' into degrees.

`\begin{gathered} (60^(\prime))/(20^(\prime))=(1\degree)/(x) \\ x=(20^(\prime))/(60^(\prime))\cdot1\degree=0.333\degree \\ \therefore20^(\prime)=0.333\degree \end{gathered}`

Therefore, we have: tan 49°20' = tan 49.333° = 1.164
