We have to determine the value of [tex] \cos 79^{\circ} 15' [/tex]
Firstly we will find the value of [tex] 79^{\circ} 15' [/tex]
[tex] 79^{\circ} 15' [/tex]
=[tex] 79^{\circ} + 15' [/tex]
Since 1 minute = [tex] \frac{1}{60}^{\circ} [/tex]
[tex] =79^{\circ} + \frac{15}{60}^{\circ} [/tex]
[tex] =79^{\circ} + 0.25^{\circ} [/tex]
[tex] =79.25^{\circ} [/tex]
Now, we have to determine the value of [tex] \cos 79.25^{\circ} [/tex]
Now, we will use calculator to find the value of [tex] \cos 79.25^{\circ} [/tex]
So we get as,
[tex] \cos 79.25^{\circ} [/tex] = 0.1865
= 0.187 (Rounded)
