Calculate the value of tan (48°19'23'').
Annette [7]

Answer:

tan (48°19'23'') => 1.1232

Step-by-step explanation:

60' minutes are present in a degree, and 60 * 60' seconds are present in a degree;

48°19'23'' = 48 + 19/60 + 23/3600

= \frac{172800}{3600}+\frac{1140}{3600}+\frac{23}{3600}

= \frac{172800+1140+23}{3600}

= \frac{173963}{3600} = 48.323°

tan(48.323°) = 1.1232
