Consider the diagram above. what is the value of m? what is the value of n?

m is equal to 90 degrees and n is equal to 115 degrees

Step-by-step explanation:

We can find m simply by noting that the supplementary angle with it is equal to 90 degrees. This makes m also 90 degrees.

For n, we have to do a bit more work. We know that interior angles of a pentagon add up to 540. So we can add all of the angles together and set equal to that. Since we don't know many of the interior angles, we can find them by looking at their supplements.

113 + 107 + n + n + 90 = 540

310 + 2n = 540

2n = 230

n = 115

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
