Answer:
75°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6 , then
sum = 180° × 4 = 720°
let x be the sixth angle, then sum and equate to 720°
150 + 100 + 80 + 165 + 150 + x = 720
645 + x = 720 ( subtract 645 from both sides )
x = 75
The sixth interior angle is 75°
Answer:
y = 3x - 9
Step-by-step explanation:
We first need to find the slope (m)
m = 
= 
= 
= 3
y = mx + b
y = 3x + b
(4, 3)
y = 3x + b
3 = 3(4) + b
3 = 12 + b
-12 -12
-9 = b
(1, –6)
y = 3x + b
-6 = 3(1) + b
-6 = 3 + b
-3 -3
-9 = b
y = 3x - 9
To check: (1, –6)
y = 3x - 9
-6 = 3(1) - 9
-6 = 3 - 9
-6 = -6

The answer are:
(-4,5)
(2,2)
(-1, -3)
(3,4)
(2,-1)
(-5,6)
Since a full circle has 360degrees and this circle only has two angles, subtract the arc of the known angle to find the arc of the unknown angle.
Angle DGF + angle DEF= 360degrees
Angle DGF + 70degrees= 360 degrees
Angle DGF = 290 degrees
The arc of the unknown angle is 290 degrees
