For number 4, we'll need a few facts to answer our question:
- Two supplementary angles add up to 180°, forming a straight angle (the angle formed by a straight line)
- The interior angles of a triangle add up to 180°
Given those, we notice that the one unlabeled angle in the figure shares a line with 156°. In fact, this angle is <em>supplementary</em> to 156°, which means that the two add up to 180°. To find the measure of this mystery angle, we can subtract 156 from 180 to obtain 180 - 156 = 24°.
Now, let's look at the triangle. We already know the measure of one of the angles is 24°, and the other two are x°. What else do we know about the angles of a triangle? From the two facts listed at the beginning, we know their interior angles add up to 180°, so let's use that fact to solve for x.
We have:

, or

Solving for x:

So, x = 78°.
For question 5, the <em>definition</em> of a pair of parallel lines is a pair of lines which <em>never intersect</em>, so "always" would be the appropriate answer.
1.75 gallons of water because one gallon holds 16 cups of water.
Mark has 32 marbles and John has 96 marbles. If you add the marbles together they both have a total of 128.
The Y-intercept is showing how many candy bars were sold in 2000 since x is every year after 2000 (hope that makes sense)
Answer: Look below. I hope this helps=3
Step-by-step explanation: Sales tax is an additional amount of money you pay. based on a percentage of the selling price of goods. Also services that are purchased. For example, if you purchase a new television for $400 and live in an area where the sales tax is 7%. Then you would pay $28 in sales tax.
