Answer: what?
i dont know
Step-by-step explanation: what is the B and C group give more info plzzz.
8 sin2x - 10sinxcosx = 8*2sinXcosX-10sinXcosX = 16sinXcosX - 10sinXcosX = 6sinXcosX=3sin2x
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.
Answer:
90 hope this helps
