Answer:
The answer to your question is:
Step-by-step explanation:
m ∠ 1 = 27°
m ∠ 1 and m ∠ 2 are supplementary
m ∠ 1 + m ∠ 2 = 180°
27° + m ∠2 = 180°
m ∠ 2 = 180° - 27°
m = 2 = 153°
For functions, it's solutions.
Answer:
1={5 and 3} 2={0} 3={0.209 and 4.791} 4={-3 and 4} 5={1 and 9} 6={-4.303 and -0.697}
Step-by-step explanation:
Your probably confused on what a, b, and c means.
The problems are written like this.

That formula finds the zeros.
For example 1:

Then use the formula

If plus then 5, if minus then 3
