Find x (in degrees) in the following quadrilateral.

Mathematics
1 answer:
Ber [7]2 years ago
5 0

Answer:

x = 110°

Step-by-step explanation:

The sum of the interior angles in a quadrilateral is 360°. This means:

x + x + x - 30 + 1/2x + 5 = 360° - we can simplify this

3 1/2x - 25 = 360° - now add 25 to both sides

3 1/2x = 385 - finally divide both sides by 3 1/2

x = 385 ÷ 3.5 = 110

x = 110°

Hope this helps!

(Create a table then plot the points)


X | 0 | 1 | 2 | 3 |

-------------------------

Y | -1 | 3 | 7 | 11 |


4 (0) -1 => 0 - 1 = -1

4 (1) -1 => 4 - 1 = 3

4 (2) -1 => 8 - 1 = 7

4 (3) -1 => 12 - 1 = 11


Just apply the table method to the others and you should be fine! :)

What is the difference of the fractions? Use the number line and equivalent fractions to help find the answer.
tresset_1 [31]

Answer:

-3/4

Step-by-step explanation:

change them to improper fractions

-5/2 - (-7/4)

now multiply -5/2 by two so the denominators are the same

-10/4 - (-7/4)

subtracting a negative number is the same as adding a positive number

-10/4 + 7/4

= -3/4
