What is the measure of arc xy

Answer:

A. 46^{\circ}

Step-by-step explanation:

We have been given an image of a circle and we are asked to find the measure of arc XY.

We will use intersecting secants theorem to solve our given problem, which states that measure of an angle formed inside a circle by two intersecting secants is half the sum of intercepted arcs.

So we can set an equation to find the measure of arc XY as:

42^{\circ}=\frac{1}{2}\text{(Arc XY+Arc UV)}

42^{\circ}=\frac{1}{2}\text{(Arc XY}+38^{\circ})}

2*42^{\circ}=2*\frac{1}{2}\text{(Arc XY}+38^{\circ})}

84^{\circ}=\text{(Arc XY}+38^{\circ})}

84^{\circ}-38^{\circ}=\text{Arc XY}+38^{\circ}-38^{\circ}

46^{\circ}=\text{Arc XY}

Therefore, measure of arc XY will be 46 degrees as well and option A is the correct choice.

Which integer is closest to 0 on the number line?
IrinaVladis [17]

An integer is close to zero if it is "small".

By small, we mean that it is small in absolute value. In fact, for any given distance d, there are two integers that are d units away from zero: d and -d.

So, for example, -6 is close to zero than 8, because -6 is six units away from zero, while 8 is eight units away from zero.

So, the answer is B, -8, because it is 8 units away from zero. The other options A, C and D are, respectively, 12, 10 and 14 units away from zero.
