Answer:
C. r = d/2
Step-by-step explanation:
The radius is half of the diameter.
The diameter divided by 2 would equal the radius of a circle.
Answer:
A ray is known as a half-infinity line. As it starts from a point while the other end is pointing towards the direction till infinity.
As already discussed ray shows a direction as well, therefore, it is a vector quantity and is denoted by an arrow over the line name.
As shown below a ray can be drawn. therefore, which is starting from point A and continuing toward the right side infinity.
Step-by-step explanation:
I know math :)
theta is in the fourth quadrant where the cosine is positive.
the third side in the triangle = sqrt (4 - 2) = sqrt2
So sin theta = -sqrt2/2 = Second choice (negative because sine is negative in 4th quadrant)
tan theta = - sqrt2 / sqrt2 = -1
