A is the correct answer. A coefficient is just a number that appears in front of a variable. Please note that a number that doesn't have a variable behind it is still a coefficient since there is technically a variable behind it with a power of 0.
This is what the graph would look like
The person who explained the answer because you can see how they got the answer or the evidence they used to get the answer
It would rotate 360 degrees because 18 seconds is twice the amount of 9 seconds, so you need to multiply 180 by 2, which is 360, or one full rotation.
Answer:
∠ 4 = 80°
Step-by-step explanation:
∠ 5 and 100° are vertical angles and are congruent , so
∠ 5 = 100°
∠ 4 and ∠ 5 are same- side interior angles and sum to 180° , that is
∠ 4 + ∠ 5 = 180°
∠ 4 + 100° = 180° ( subtract 100° from both sides )
∠ 4 = 80°
