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 ( sides of a hexagon ) , then
sum = 180° × 4 = 720°
(a)
let x be the sixth interior angle , then
90° + 100° + 110° + 120° + 130° + x = 720 , that is
550° + x = 720° ( subtract 550° from both sides )
x = 170°
(b)
the sum of the exterior angles of a polygon is 360°
exterior angle + interior angle = 180°
exterior angle = 180° - interior angle
Then
180° - 90° = 90°
180° - 100° = 80°
180° - 110° = 70°
180° - 120° = 60°
180° - 130° = 50°
180° - 170° = 10°
sum = 90° + 80° + 70° + 60° + 50° + 10° = 360° ← correct total
Step 1. multiply the bottom to the other side
3=(5x+5)/(11)
Step 2. multiply the eleven to the other side
33=(5x+5)
Step 3. subtract the 5 to the other side
28=5x
Step 4. divide by 5
x=28/5 or 5.6
hope that helps!
Answer:
f(x) = -.4x + 6
explanation:
Simply find the slope using the formula
The b value can be found by substituting a point and then isolating b, the point i used was (1, 5.6) because that was the closest point to the start of the graph
