The answer is b.6, you set up a proportion of the corresponding sides in both triangles...12/9=8/x solve for x and get 6.
2: 4 is a factor and multiple of 8. 8 and 4 is also even numbers so is is most likely to be divisible by any number
Answer:

Step-by-step explanation:
We are given the two functions:

And we want to find:

So, by substitution, we acquire:

Distribute:

Simplify:

So, the first blank is for what kind of angle it is: acute, obtuse, reflex, straight, or right. The second blank is for what the measure of the angle is. You can find that out by looking at the protractor. It should tell you what the measure of the angle is. You can read the protractor by looking at the numbers. The numbers are the degrees of incline the angle measures, which is what you're looking for.
