Answer: c. 48°

Step-by-step explanation:

From the diagram above, taking the circle in an anti-clockwise direction, we can say, ZX =228° and XZ = 132°

Using the outside angle theorem;

<y = (ZX - XZ) / 2

<y = (228 - 132) / 2

<y = 96 / 2

<y =48°

Therefore, the measure of angle y is 48°

If we draw in  OX, OY, OZ we have two congruent right triangles, right angles at the tangent points.

We know XOZ is 132 degrees, which is the meaning of the arc measure

So YOX is half that, 66 degrees.

That leaves 180 - 90 - 66 = 24 degrees for OYX

Angle Y aka XYZ is double that, 48 degrees.

Answer: C

What is the value of A?
Artemon [7]

Answer:

101

Step-by-step explanation:

The theorem to use this is the intercepted arc theorem, which tells us that if we take 2 points on the circumference of a circle and create an angle in the opposite side of the circumference, that angle is HALF that of the ARC intercepted.

If we look at 100 degree angle, we see the ARC intercepted is 99 degree and a degrees. According to theorem, we can say:

99 + a = 2(100)

99 + a = 200

a = 200 - 99

a = 101

The second quartile of a data set is 4.2. Which statement about the data values is true?
Setler [38]
The second quartile is also the median. which is 50% of the data. So 1/2 of the data lies below it, and 1/2 of the data lies above it.
the correct answer would be A. the data value of 2.5 will lie below the second quartile.
