Can you guys please help me with my homework please do not answer if you do not know the answer at all I’ll give brainliest answer I need help with angles please someone help!!

Answers

Answer and Step-by-step explanation:

For the triangles, all you have to do is subtract the two angles by 180 to find the missing angle.

2.

180 - 54 - 85 = 41

3.

180 - 36 - 59 = 85

4.

The square on the bottom represents a right angle, and right angles are always 90 degrees.

180 - 90 - 54 = 36

14. Mrs. Buchanan is planning marching routines for the school band. The band has 36 members. Band members can march in any number of rows as long as each row has the same number of members. The marching path, however, limits members to 6 per row.

Answers

Question:

Make a list of the different arrangements that Mrs. Buchanan could use.

Answer:

[tex](x,y) = \{(1,36),(2,18),(3,12),(4,9),(6,6)\}[/tex]

Step-by-step explanation:

Given

[tex]Members = 36[/tex]

[tex]Rows\ Limit = 6[/tex]

Represent the rows with x and the column, y.

This means that:

[tex]x * y = 36[/tex]

Make y the subject:

[tex]y = \frac{36}{x}[/tex]

The list is then generated as follows:

When x = 6.

[tex]y = \frac{36}{6} = 6[/tex]

[tex](x,y) = (6,6)[/tex]

When x = 5

[tex]y = \frac{36}{5} = 7.2[/tex]

This result can not be use because the result of the number of columns must be an integer

When x = 4

[tex]y = \frac{36}{4} = 9[/tex]

[tex](x,y) = (4,9)[/tex]

When x = 3

[tex]y = \frac{36}{3} = 12[/tex]

[tex](x,y) = (3,12)[/tex]

When x = 2

[tex]y = \frac{36}{2} = 18[/tex]

[tex](x,y) = (2,18)[/tex]

When x = 1

[tex]y = \frac{36}{1} = 36[/tex]

[tex](x,y) =(1,36)[/tex]

So, the possible list is:

[tex](x,y) = \{(1,36),(2,18),(3,12),(4,9),(6,6)\}[/tex]

Answer:

1: x = 47, y = 902: x = 92, y = 88, z = 923: 284: x = 90, y = 855: 133

Explanation:

[1] - A

y = 90 (90 degree angle)

90 - 43 = 47, so x = 47

[2] - C

x = 92 because 180 - 88 = 92

x = 92 and y = 88 because 92 + 88 = 180

[3] - C

x = 28 because 90 - 62 = 28

[4] - D

x = 90 because 180 - 90 = 90

y = 85 because 42 + 53 = 95, 180 - 95 = 85

[5] - A

x = 133 because 180 - 47 = 133
