the answer is -1 and 3

then what 2 numbers multiply to get 8

(2x-1)(4x+3) is the factored form

**Answer:**

<u>**-289 degrees**</u>

**Step-by-step explanation:**

You are looking for what is called <u>**Coterminal Angles**</u>.

To find a coterminal angle between 0 and 360 you <u>add or subtract</u> 360.

- In this case, we subtracted 360 from 71
- 71 - 360 = -289
- tan(-289) = 2.90
- If TAN 71 = 2.90 and TAN -289 = 2.90, you know -289 is your answer.
