Step-by-step explanation:
Answer:
6
Step-by-step explanation:
6
Answer:
A
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
n is an exterior angle of the triangle.
The 2 opposite interior angles are
180° - 131° = 49° and 180° - 160° = 20°, thus
n = 49° + 20° = 69° → A
Answer: adjacent, adjacent & complimentary
<u>Step-by-step explanation:</u>
→ ∠CEA and ∠CEF share a common side so they are adjacent
The sum of their angles is not 90° or 180° so they are not complimentary or supplementary. They are not across from each other so they are not vertical.
→ ∠FEB and ∠BED share a common side so they are adjacent.
→ The sum of their angles is 90° so they are complimentary.
The sum of their angles is not 180° so they are not supplementary. They are not across from each other so they are not vertical.
