Answer:
I think it goes like this:
4x+5x=180
9x=180
x=180:9
x=20
Step-by-step explanation:
Let's use the process of elimination:
We know the bottom two are incorrect, because numbers that are divisible by 9 ARE divisible by 3.
Take 18 for an example. 18 is divisible by 3 (3 * 6 = 18), and 9 (9*2 = 18).
Some of the numbers that are divisible by 9 are also divisible by 3 isn't the best statement, because we know that all multiples of 9 are divisible by 3.
Now we have 2 of them.
I think it's the second one, because the first one doesn't explain the details between the relationship of 9 and 3 (as well as the second one).,
So I think it's the second from the top.
(A number that is divisible by 9 is also divisible by 3, because all factors of 9, are factors of 3.)

Answer:
36°
Step-by-step explanation:
By remote interior angle theorem:
b + 81° = 117°
b = 117° - 81°
b = 36°
