Select one or more expressions that together represent all solutions to the equation . Your answer should be in radians . Assume n is any integer. 18cos(10x)+2=10

θ =  5.6251 + n*2π

Step-by-step explanation:

Given the expression

18cos(10x)+2=10

18cos(10x) = 10 -2

18cos(10x) = 8

cos(10x) = 8/18

cos(10x) = 5/9

10x = arccos(5/9)

10x = 56.251

x = 56.251/10

x = 5.6251

For cos theta

θ=cos^-1a+n*2π

θ = 5.6251 + n*2π

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

answer:

a=9
