Step-by-step explanation:
<u>Given:</u>
- Rule, x + 7.
- Table values.
The rule is telling us to add 7 to the given value of x.
Add 7 to 12.

The missing number is 19.
Answer:
-4
Step-by-step explanation:
Slope = y2 - y1/x2 - x1
Given
x1 = 6
y1 = 2
x2 = 4
y2 = 10
Therefore
Slope = 10 - 2/4 - 6
= 8/-2
= -4
180° - 36° - 39° - 33° = <u>7</u><u>2</u><u>°</u>
x° = 180° - 72°
x° = <u>1</u><u>0</u><u>8</u><u>°</u>
So, the value of x is 108°
