Answer:
1). x° + 100° + 120° + 100° = 360°
2). x = 40
Step-by-step explanation:
Formula for the sum of the interior angles of a polygon =
Where n = number of sides of the polygon
From the picture attached,
For n = 4,
Sum of the interior angles of the given polygon = (4 - 2) × 180°
= 360°
Therefore, equation for the sum of interior angles will be,
x° + 100° + 120° + 100° = 360°
x° + 320° = 360°
x° = 360° - 320°
x° = 40°
Do 12 2/3+10 2/3 which is 23 1/3 than subtract 8 2/3 for your answer.
11, 12, 13, 14, 15, 16, 17, 18, 19 Sorry if it doesn't help, I'm being too obvious
You can multiply each fraction on both top and bottom so that they have 24 as the denominator. The equation becomes
subtract 16/24 to both sides and you get
now subtract 20/24 from both sides and
<u />
multiply 24 on both sides
-26=21m
and divide by 21 on both sides
m=-26/21 or -1.24
