Answer:

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.
