Solve each triangle - find any missing side and angle measures. Round answers to the nearest tenth.
Basile [38]

The sides of the right-angle triangle will be 16 units and 20.30 units. And the missing angle will be 52°.

<h3>What is a right-angle triangle?</h3>

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The side AC will be

tan 38° = 12.5 / AC

      AC = 15.999

      AC ≈ 16 units

Then the side AB will be

AB² = 12.5² + 16²

 AB = 20.30 units

We know that the angle sum is 180 degrees. Then we have

∠A + ∠B + ∠C = 180°

38° + ∠B + 90° = 180°

                  ∠B = 52°

More about the right-angle triangle link is given below.

1. Mr.Customs is correcting the class’s math homework on customary units. Which of the following measurements is reasonable?
frosja888 [35]

Answer:

The reasonable measurement in question 1 is D - the distance from New York to California is 2,250 miles.  The best unit of measurement for the length of the distance of your textbook is A - inch.  

Step-by-step explanation:

The United States uses the Imperial System of measurement which uses things such as inches, feet, yards and miles.  In order to understand reasonable measurements, you need to first realize the order in which size would be determined.  For instance, 12 inches is equal to one foot, which can be found on your typical ruler.  Additionally, three feet is equal to one yard, which we can find on a yard stick.  Lastly, there are 1,760 yards in one mile, which is typically measured with some time of pedometer/odometer.  So, when you think about calculating measurement for common things such as a pencil or distance between cities, think about whether this distance could be measured using a ruler or perhaps the odometer on a car.

A group of 100 people is divided into 2 teams with 45 people in team A and 55 people in team B.
Zepler [3.9K]
Team A) 45 people
Team B) 55 people

A)There are two ways to solve this problem, finding the number of combinations possible for Team B, or the number of combinations possible for Team A. 
Team A
It's a given that 20 mathematicians are on team A, which leavs the other 25 people for team A to be chosen from a pool of 80 (100- 20 mathletes)
80-C-25 = 80! / (25!/(80-25)!) =<span>363,413,731,121,503,794,368
</span>or 3.63 x 10^20
Solving using Team B
Same concept, but choosing 55 from a pool of 80 (mathletes excluded)
80-C-25 = 80! / (55!(80-55!) = 363,413,731,121,503,794,368
or 3.63 x 10^20

As you can, we get the same answer for both. 

B)
If none of the mathematicians are on team A, then we exclude the 20 and choose 45:
80-C-45 = 80! / (45!(80-45)!) = <span>5,790,061,984,745,3606,481,440
or 5.79 x 10^22

Note that, if you solve from the perspective of Team B (80-C-35), you get the same answer</span>
