cos(37°15') = cos(37.25°) ≈ 0.7960
15' means 15/60 of a degree, or 0.25 degrees.
_____
Note: the calculator mode is set to Degrees.
Answer:
cos(37°15')=0.7960
Step-by-step explanation:
Evaluate cos(37°15').
First we convert 15' into degree
60' = 1 degree, to convert 15' to degree we divide by 60
So 15' = [tex]\frac{15}{60} =0.25[/tex] degree
cos(37°15')=cos(37° +0.25°)= cos(37.25°)
Now we use calculator to find the value of cos(37.25°)
Put the calculator in degree mode
cos(37.25°)=0.7960
