Answer is 10 and 170, complementary angles are 90°, while supplementary angles are 180 in total, if angle A is 80 then you subtract 90 by 80 and you get 10, so that is angle B, So then you are asked what is angle C. Which is part of the supplementary angle so you take the 10° that you got from B and then you subtract 180 by the 10, And thats how you get 170 and that's how you know that C is 170 (hope this explanation helps)

What do you think Thomas Edison meant by the word perspiration? How do those words apply to what you've learned about businesses

EastWind [94]

1. Thomas Edison used "perspiration" to refer to the physical and mental efforts needed to achieve a meaningful purpose in any human endeavor.

2. As it applies to businesses, it is not enough to develop a business idea or plan, as the business person must be prepared to execute and carry the business idea or plan to fruition.

<h3>What does Thomas Edison's reference mean?</h3>

According to Thomas Edison, the superior intellect or creativity we associate with great minds comes from inspiration (the idea) and perspiration (hard work).

Perspiration literarily refers to the sweat that emanates as someone works hard.

Without a strong working ethic, it will be impossible to achieve great results from only the proposition of great ideas or business plans.

H = {(2, 5), (3, 5), (4, 5), (5, 5), (6, 5)} Is H a function and why?.

mixer [17]

Answer:

Yes, each x-value has a unique y-value.

Step-by-step explanation:

This is a function because each x-value has its own y-value. If this is not the case then it is not a function, because then, two points with the same x-value and different y-values would fail the VLT.

Your graph does not have overlaps and each x-value has a unique y-value

VLT

The vertical line test (VLT) is a simple method that mathematicians made because they were lazy to make a table of values and find duplicates.

Passing the VLT means that if you drew a vertical line anywhere on the graph, it would only go through one point.
Failing the VLT would mean that the vertical line

A quick way to check if it is a function is by looking for duplicates of x-values and check that the duplicates have the same y-value.
