Question

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

Answer 1

Answer:

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

Step-by-step 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:

$\sec 37^{\circ} = \frac{1}{\cos 37^{\circ}}$

$\cos 37^{\circ} = \frac{1}{\sec 37^{\circ}}$

$\cos 37^{\circ} =\frac{1}{1.25}$

$\cos 37^{\circ} = 0.80$

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