Supplementary angles add to?

Advanced: Write an equation and solve for x in the diagram

Supplementary angles add up to 180 degrees.

7x + 3x = 180 degrees.

Combine like terms.

10x = 180 degrees.

Divide both sides by 10

x = 18

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
