Beck used a compass and straightedge to accurately construct line segment os as shown in the figure.

which could be the measures of angle pos and angle poq?

a) m∠pos = 60° , m∠poq = 120°
b) m∠pos = 50° , m∠poq = 110°
c) m∠pos = 50° , m∠poq = 120°

Based on the given figure above, we can find the measures of angle POS and angle POQ by analyzing it carefully. Look for POS and POQ where POS = 1/2 POQ. Base on this, we can conclude that measure of angle POS = 60° and measure of angle POQ = 120°. Therefore, the answer would be option A. 

Observe the figure below.

The given figure shows that the construction of line segment OS. We can observe clearly that OS is bisector of angle POS.

The bisector divides the angle into two equal angles.

So,

Let us observe the given options.

In first option,

Therefore,

So, Option A is the correct answer.

She will need to buy 3 packs to make 6 different balloon animals.

Step-by-step explanation:

Given that the balloon artist wants to make 6 different animals, and each animal involves using 4 balloons, to make those 6 animals she must use 24 balloons, as the following calculation shows:

6 x 4 = 24

Now, since the balloons come in packs of 8 units, to make those 6 animals she must buy 3 packs of balloons, as this calculation also shows:

24 / 8 = 3.
