Identify the reference angle ∅ for each given angle, 0.
frutty [35]

Answer:

When Ø = 300°, Ø = 60 degrees.

When Ø = 225°, Ø = 45 degrees.

When Ø = 480°, Ø = 60 degrees.

When Ø = -210°, Ø = 30 degrees.

Step-by-step explanation:

Reference angles are in Quadrant I (0° to 90°).

1. Find 300° (Quadrant IV) on the unit circle. Since it's in Quadrant IV, you use 360 - 300 = 60° to get your answer.

2. Find 225° (Quadrant III) on the unit circle. Since it's in Quadrant III, you use 225 - 180 = 45° to get your answer.

3. The angle 480° is not on the unit circle. To find its corresponding angle between 0° and 360°, use 480 - 360 = 120°. Then, find 120° (Quadrant II) on the unit circle. Since it's in Quadrant II, you use 180 - 120 = 60° to get your answer.

4. The angle -210° is not on the unit circle. To find its corresponding angle between 0° and 360°, use -210 + 360 = 150°. Then, find 150° (Quadrant II) on the unit circle. Since it's in Quadrant II, you use 180 - 150 = 30° to get your answer.

Need help in algebra fast
Gennadij [26K]

Answer:

A

Step-by-step explanation:

This is a strict inequality so the line must be dotted, meaning it can only be A or D.

The inequality says that y is less than -2x+4 so we want the region under the line, making A the correct answer.

Paha777 [63]
Ok so the rise is the 6 and 172 is your run which this is how to find the slope using the fraction/ equation rise/ run which gives you the answer of 28.666666 and on and on which is not an acceptable slope I believe the question is a little confusing   <span />

Please help me with this question please
sesenic [268]
Your answer is right. to solve it you would move the 10 over to get 10x^2-29x+10=0. i would solve by chunking and breaking -29x into -25x and -4x. This will give us (10x^2-25x)+(-4x+10). now factor both get inside the parenthesis the same. 5x(2x-5)+-2(2x-5). Now combine the factors you took out with what is inside to get (5x-2)(2x-5)
