Consider each statement about finding the measurements of triangles. Choose True or False for each statement.
A. If you know the measures of the three angles of a triangle, you can find the lengths of the sides.
True or False
B. If you know the lengths of the three sides of a triangle, you can find the measures of the angles.
True or False
C. If you know the measures of the two sides of a triangle and the measure of an angle not included between the two sides, you can solve the triangle. True or False
Answer:
c
Step-by-step explanation:
Measurement of triangle
Measure of 3 angles find length is true.Lengths of 3 sides for angles is true.Measures of angles not included the two sides is false.What is the measure of the triangle?The measure of the triangle is the sum of 3 interior angles of the triangle. This is always 180 degrees, as a triangle has 3 sides and 3 angles.
The measure of the three sides of the triangle can help in finding out the angles and similarly the three angles can help to find the length. If we consider two sides and then measure the angle then the triangle can't be solved.

What is the period of 1-sin 2πx/3? Please explain.
Answer:
Notice, period of function sin(kx) is 2π/k where k is constant (coefficient of x ) since coefficient of x in sin(2πx/3) is k=2π/3 hence the period of sin(2πx/3) is 2π/(2π/3)=3

please help find the perimeter
Answer:
Perimeter of the given figure = 28 units
Step-by-step explanation:
Perimeter of the given figure = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FG + Length of GH + Length of AH
Length of AB = 4.5 units
Length of BC = 2 units
Length of CD = 2 units
Length of DE = 4 units
Length of EF = 5.5 units
Length of FG = 1.5 units
Length of HG = 1 units
Length of AH = 7.5 units
Perimeter of ABCDEFGH = 4.5 + 2 + 2 + 4 + 5.5 + 1.5 + 1 + 7.5
= 28 units
Which of the following are accurate assessments of trends displayed in this graph?
I. Sales of teddy bears decreased by about 2.9% between September and October.
II. The change in sales of rabbits is roughly equal to the change in sales of all toys.
III. Roughly 24.1% fewer horses were sold in October than in September.
a. I and II
b. II only
c. I and III
d. III only
Answer:
✅ D. III onlygot it right on the test⬇️
The correct statement is
Roughly 24.1% fewer horses were sold in October than in September.
What is Data?Data refers to any information, regardless of how it is presented or represented. A data can be a numeric expression, a piece of text like a name or address, or it can be a number.
We have,
September October Trend
Teddy bears 346 308 -10.98%
Rabbits 297 260 -12.46%
Cats 199 285 +43.22%
Horses 245 186 -24.08%
Others 225 275 +22.22%
Total 1,312 1,314 +0.15
Now, Sales of teddy bears decreased by about 2.9% between September and October.
That reduced by around 11%, thus it is untrue.
II. The change in sales of rabbits is roughly equal to the change in sales of all toys.
It is untrue because variations in the sales of rabbits do not correspond to variations in the sales of all toys.
III. Roughly 24.1% fewer horses were sold in October than in September.
Yes, this is correct.

Answer the following questions using 125 words or more:
1. Write about the similarity of the original comic to the enlargement. How similar are they and how can you tell? What
would cause differences in the two pictures? If you drew another comic using a grid, is there anything you would do
differently?
2. What would happen if you reduced the comic's size rather than enlarged it? Would the process be the same? What
would you do differently?
The way in which the original comic would be similar to the enlargement is that they have the same proportion.
How is the original comic similar to the enlargement?Based on the fact that when a comic is enlarged, the original and enlargement would remain the same and the only difference would be a larger size.
Hence, we can see that because they have the same proportion, each individual pixel in the original is more visible and the enlargement displays the image in a small number of large pixels.
The use of a grid would likely reduce the effect of pixelation and if there is a reduction in the size of the comic, there would be the same effect, only that it would be smaller, but have the same proportion.

Step-by-step explanation:
what is the question asking
After the end of everyday, a production plant's maintenance crews check on the machinery and grade each item's state of repair. A particular robot arm can be given ve grades: Excellent, Good, Satisfactory, Watch, Failed. If the robot arm is tagged with a Failed grade, a crew will be sent the next day to repair it. There is about a 60% chance the crew will be successful in repairing the arm back to an Excellent condition. Otherwise, they have to try again the next day to x it. The general wear and tear of operation causes at most a single level of deterioration a day and this grade decrease happens about 25% of the time. During the day, the operators can tinker with the arm and are able to increase (if possible) the repair grade level 10% of the time. The operators cannot improve a Failed arm. Management wants to model the daily grade level of a robot arm.

Step-by-step explanation:
3*10=30
5*14=70
30+70=100!!!
Answer:
he sold 14 apples
Step-by-step explanation:
multiply 10 (watermelon) and 3 (the cost) which is 30
now subtract 30 from 100 which is 70
last do 5 (the cost of apple bunch) by 70 to find the total number of bunches he sold which is 14

Can someone please help meee
Answer:
90 degrees
Step-by-step explanation:
If two angles are supplementary they are a linear pair which means they form a straight line, and if you know a straight line equals 180 degrees which is the total degrees of a triangle.
Now if you have two supplementary angles and they are congruent that means not only are they right angles but its half of 180 so you divide these pair of 2 by 180 giving you your total of 90 degrees.

How do I solve 1 1/3 × 2 2/4 in steps?
Answer:
3 1/3
Step-by-Step
first step is too make a an improper fraction, 1 1/3 equals 4/3 and 2 2/4 equals 10/4. next your gonna multiply 4/3 and 10/4, 4x10=40,3x4 equals 12, so it would be 40/12. but its improper, we need to reduce it. the lowest number that can go in both numbers is 4. 40 divided by 4 =10. 12 divided by 4=3. 12/3= 3 1/3
Answer:
10/3
Step-by-step explanation:
That's 1 1/3 times 2 1/2.
Converting these into improper fractions, we get 4/3 times 5/2.
Multiplying (4/3) by (5/2), we get 20/6, or, after reduction, 10/3

The internal angle is 180o−360o / 24=180o−15o =1 65o . Half of this is 82.5o . The perimeter is now 24x so we have:
24 x /h = 24 / tan(82.5o) Rather remarkably:
So tan(82.5o) =√+2 + √+3+√+4+√+6
24 x / h = 24 / ( √+2 + √+3+√+4+√+6 ≈3 .1596599421
