Question

If the secant value is 37^ * , the cosine value to the hundredths degree is: A 0.80 B1.25 C0.60

Answer 1

The value of the cosine function at 37º is 0.80. A. 0.80

Explanation:

The correct statement is: "If the secant of 37º is 1.25, the cosine value to the hundredths degree is:"

Secant and cosine functions are related by the following trigonometric identity:

`\sec 37^(\circ) = (1)/(\cos 37^(\circ))`

`\cos 37^(\circ) = (1)/(\sec 37^(\circ))`

`\cos 37^(\circ) =(1)/(1.25)`

`\cos 37^(\circ) = 0.80`

The value of the cosine function at 37º is 0.80. The right answer is A.
