Answer:
2 pi, -2 pi, pi, -pi
Step-by-step explanation:
Draw a unit circle and label the 4 points where it intersects the x/y axis. for example at 0 degrees or 360/-360 degrees the (x,y) or (cosine theta, sine theta) value is (1,0).
Answer:
A) y=3x-4
Step-by-step explanation:
An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.
Hi there! The answer is D. kite.
A kite is a quadrilateral with four sides. These four sides can be grouped into two pairs of two sides. The sides in a pair equal in length. The two pairs of angles are adjecent to each other.
An easy way to recognise this mathematical shape is by comparing it to a kite in real life (a kite is a frame covered with paper or plastic, designed to be flown in the air).

Answer:
C
Step-by-step explanation:
Notice that there is a little triangle formed by the lines on the right side of the diagram.
Let's find the angle measures of the triangle. One of them has a supplementary angle of 96 degrees, which means that the actual interior angle is 180 - 96 = 84 degrees.
Another angle has a supplementary angle of 137, which means that the actual interior angle of the triangle is 180 - 137 = 43 degrees.
Finally, we have the expression 2x - 23, which is an exterior angle. By definition, this exterior angle is equal to the sum of the interior angles of the triangle that do not include its supplementary angle. In other words:
2x - 23 = 84 + 43
Now we just solve for x:
2x - 23 = 84 + 43 = 127
2x = 127 + 23 = 150
x = 150/2 = 75 degrees
The answer is 75 degrees, or C.
