Since angle a is 143° you’d subtract 143 by 180 because a supplementary angle is 180° which would give you 37° for angle b
Answer: 37°

Boxes that are 12 inches tall are being piled next to boxes that are 10 inches tall. What is the least
zysi [14]

Answer:

60 inches

Step-by-step explanation:

the least common multiple of 12 and 10 is 60

you can use the prime factorization tree or a list method

1st multiple of 10: 10                               1st multiple of 12: 12

1st multiple of 10: 20                               1st multiple of 12: 24

1st multiple of 10: 30                               1st multiple of 12: 36

1st multiple of 10: 40                               1st multiple of 12: 48

1st multiple of 10: 50                               1st multiple of 12: 60

1st multiple of 10: 60                              

You can stop when a common multiple is reached

The equation below was identified as representing the relationship between dollars spent
ankoles [38]

Answer:

The company should spend 20,000 dollars on advertising in order to avoid losing money.

Step-by-step explanation:

You know that the relationship between dollars spent on advertising X, and earnings P, for a particular company is:

P= 1.5* X -30,000

You want to know how much money the company should spend on advertising so that the company doesn't lose money. That is, the company has no losses but no profits. So this means that P must have a value of 0.

So, replacing:

0= 1.5*X - 30,000

Solving:

30,000= 1.5*X

30,000÷ 1.5= X

20,000= X

<u><em> The company should spend 20,000 dollars on advertising in order to avoid losing money.</em></u>

Identify the correct explanation for why the triangles are similar. Then find OP and MN.
STALIN [3.7K]

Answer:

Therefore, the correct explanation is;

C. ∠L ≅ ∠L  By Reflexive Prop. ≅.

Since \overline {OP} ║ \overline {MN}, ∠LOP ≅ ∠LMN by the Corr. ∠s Post. Therefore, ΔLOP ~ ΔLMN by AA ~. OP = 4 and MN = 8

Step-by-step explanation:

The given parameters are;

\overline {LP} = 5

\overline {NP} = 10

\overline {OP} = x - 3

\overline {MN} = x + 1

A two column proof is presented as follows;

Statement    {}      Reason

∠L ≅ ∠L     {}        By Reflexive property of congruency

\overline {OP} ║ \overline {MN}     {}     Given

∠LOP ≅ ∠LMN {}  By the Corresponding angles Postulate

Therefore

ΔLOP ~ ΔLMN {}  By AA similarity Postulate

Where we have that ΔLOP and ΔLMN, we get;

\overline {OP}/\overline {MN}  = \overline {LP}/\overline {NP} = 5/10 = 1/2

∴ (x - 3)/(x + 1) = 1/2

2·(x - 3) = 1·(x + 1)

2·x - 6 = x + 1

2·x - x = 1 + 6 = 7

x = 7

\overline {OP} = (x - 3) = 7 - 3 = 4

\overline {OP} = 4

\overline {MN} = x + 1 = 7 + 1 = 8

\overline {MN} =  8

Therefore, the correct option is ∠L ≅ ∠L  By Reflexive Prop. ≅.

Since \overline {OP} ║ \overline {MN}, ∠LOP ≅ ∠LMN by the Corr. ∠s Post. Therefore, ΔLOP ~ ΔLMN by AA ~. OP = 4 and MN = 8.
