Answer:

53˚

Step-by-step explanation:

There are 360 total degrees in a 4-sided shape (You can find the total number of degrees in a polygon by using the formula 180(n – 2) where n is the number of sides).

so we can add up all the degrees and subtract them from 360.

67 + 135 + 105 = 307

360 - 307 = 53

Which of the following best describes the set of all numbers of the form a+bi where a and b are any real numbers and i equals sq

Andrei [34K]

<h3>Answer: B) Complex numbers</h3>

Complex numbers are always in the form a+bi with 'a' and 'b' as real numbers.

If b = 0 and 'a' is nonzero, then a+bi = a+0i = a which is strictly a real number

If a = 0 and b is nonzero, then a+bi = 0+bi = bi indicating that the number is now purely imaginary

What is the sum of 1/4 and 1/5?

krok68 [10]

To add them, you first need a common denominator.
So multiply 1/4 by 5/5 and 1/5 by 4/4 first.

Now they'll be 5/20 and 4/20.

Add them to get 9/20.

Left to Right

Algebra I

Coordinates (x, y)
Parallel lines have the same slope but different y-intercepts
An undefined line is a vertical line
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (3, 2)

Point (3, 1)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{1-2}{3-3}$
[Fraction] Subtract: $\displaystyle m=\frac{-1}{0}$
Simplify: m = undefined
