Answer:
53°, 127°, 127°
Step-by-step explanation:
<u>Two intersecting lines form two pairs of angles:</u>
- Pair of vertical angles. They are opposite to each other and are equal
- Pair of adjacent angles which are supplementary angles and their sum is 180°
<u>So if one of the angles is measured 53°, then the other angles are:</u>
- 53°- vertical angle with the first one
- 180° - 53° = 127°
- 180° - 53° = 127°
(-3x^2 - 5x + 1) + (8x^2 - 2x - 9)
1st remove the parenthesis
-3x^2 - 5x + 1 + 8x^2 - 2x - 9
then combine like terms
5x^2 - 7x - 8 is the final answer
