Answer:

30 degrees

Step-by-step explanation:

The sum of exterior angles = 360 degree

102 + 73 + 67 + 88 + a = 360

330 + a = 360

a = 360 - 330

a = 30 degree.

Answer:

a = 30

Step-by-step explanation:

The total exterior angles of a pentagon is 360 degrees, meaning:

102 + 73 + 67 + 88 + a = 360

330 + a = 360

Subtract 330 from both sides:

330 + a - 330 = 360 - 330

a = 30

Hope this helps!

Can someone help solve
leva [86]

\frac{-18z^{7}y^{5}-9z^{9}y^4+18z^6y^8}{9zy^{2} }= -2z^6y^3-z^8y^2+2z^5y^6


When variables with exponents are divided by each other, you subtract the exponents.

For example:

\frac{x^2}{x^1} = x^{2-1} =x^1

\frac{x^5}{x^3} =x^{5-3} = x^2

trasher [3.6K]

When an answer to a question uses the greater than symbol, that means any number above the number used is a possible answer to the equation. However, when it's just a simple "x = 2", then 2 is the only possible answer to that equation. Think about it as if it were on a graph. In the attached file I have a graph that is displaying the equation "x > 4". The entire shaded area to the right of 4 could be a possible answer.

Hope this helps.

What are the missing reasons in the two-column proof?
Nesterboy [21]

Reasons:

1. Because, MO cuts Angle PMN in two equal parts.

2.As ∠PMN is cut in to equal parts thus:

∠PMN = ∠NMO + ∠PMO, where these two parts (∠NMO, ∠PMO) are equal.

3. Both are the same, common you can say..

4. Because, MO cuts Angle PON in two equal parts.

5. As ∠PON is cut in to equal parts thus:

∠PON = ∠NOM + ∠POM, where these two parts (∠NOM , ∠POM) are equal.

6. From the above statements, we have:

= ∠NMO + ∠PMO (Proved)

= ∠NOM + ∠POM (Proved)

= MO = MO (Proved)

Thus, ∆PMO ≅ ∆NMO, by AAS rule

Answer:

Fictitious account receivable

Step-by-step explanation:

Fictitious account receivables involves creating fake accounts or fake sales for the purpose of having the company appear to be in a better financial condition. This can be by creating fake invoices for fake customers.

These malicious activities are carried out by employees for the purpose of having an increase in sales commission.

The quick ratio that has suddenly increased from 1.7 to 2.3 can be due to the creation of these fictitious accounts and sales.
