find the missing value to the nearest hundredth.
cos_=10/38
a.74.74
b.15.26
c.14.74
d.50.37

Option a

Step-by-step explanation:

The missing term is the angle that goes in the argument of the cosine function.

Let's call this angle x.

So the equation is:

now we must solve the equation for x

then we apply the inverse function of cos(x) on both sides of the equality

The answer is the option "a"

substitute the numbers.

-3 + 6 - 1

= 2
