2 answers:

6 0

You can try by plugging each ordered pair and seeing if the equation comes out true.

(5, 1)

2 * 5 - 1 = 9

That's correct so C is the correct answer.

How could you explain the sine and cosine relationships to someone who doesn't know about the unit circle? What visuals could yo

sukhopar [10]

If you have a unit circle, it means that you have a circle of radius r = 1 unit. So if we consider the scalene triangle of the figure, its vertical side is the sine of the theta angle and its horizontal side is the cosine of the theta angle. Then to find the hypotenuse of the triangle you use the Pythagorean theorem, thus relating the sine and cosine measures. I attach the solution.

1. Alternate exterior angles

So, C

2.
180 = 76 + 2x
104 = 2x
52 = x

So, B

4.

4a. No
4b. Yes
4c. No
4d. Yes

5.
180 = 35 + 35 + 2x
180 = 70 + 2x
110 = 2x
55 = x

So, C.

7.

12/8 = 30/y

Cross multiply

12y = 240
y = 20

So, C

8. Alternate interior angles

So, A
