You can add up the angles that are labeled(73,110,and 90 because of the right angle) and get 273.

For a quadrilateral, all of the angles add up to 360.

So, subtract 360-273.

You get 87.

I have $460 less than dotun. Altogether we have $1280. How much do we have

Answers

Answer:

you have $180, total there is $1280

Step-by-step explanation:

The required amount we have is given as $410, as of the given condition.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

here,
Let the amount we and Dotun has to be x and y,
According to the question,
x  = y - 460- - -- - -(1)

x + y = 1280 - - - (2)
From equation 1
y - 460 + y = 1280
2y = 1280 + 460
y = 1740/2
y = $870

Now,
x = 870 - 460
x = $410

Thus, the required amount we have is given as $410, as of the given condition.

Prove that there is no complex number such that | z | −z = i​

Answers

This is the answer for the question

The proof is shown below:

What is complex number?

A complexb number is the of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z. Here both a and b are real numbers. The value 'a' is called the real part which is denoted by Re(z), and 'b' is called the imaginary part Im(z).  Also, ib is called an imaginary number.

The alphabet i is referred to as the iota and is helpful to represent the imaginary part of the complex number. Further the iota(i) is very helpful to find the square root of negative numbers.

We know

z= a +ib

and |z|= √a² + b²

So, |z|-z =i

√a² + b² - a- ib=i

Now, comparing the coefficients

b=-1

√a² + b² - a = 0

√a² + (-1)² - a=0

√a² + 1 - a = 0

√a² + 1 = a

a² + 1 = a²

1= 0

Which is not possible.

Hence, there is no complex number such that | z | −z = i​

3(2 + 9)

Step-by-step explanation:

The numbers 6 and 27 can be written as factored as

6 = 2 * 3

27 = 3 * 3 * 3

The both have one factor of 3 in common.

The greatest common factor (the GCF) of 6 and 27 is 3.

Now we factor out 3. To do that, we divide both 6 and 27 by 3.

6/3 = 2

27/3 = 9

We see that

6 + 27 = 3 * 2 + 3 * 9,

and the common factor of 3 is in both multiplications.

Finally, we factor out the 3, leaving the results of the divisions inside the parentheses.

6 + 27 = 3 * 2 + 3 * 9 = 3(2 + 9)

Answer: 3(2 + 9)
