Answer:
Slope of (0,2) and (-8,-8): 5/4
Slope of (-8,-5) and (8,15): 5/4
Both slopes are 5/4
m = 5/4
Step-by-step explanation:
To find the slope:
1. Use the formula .
2. Assign point 1 and point 2
3. State (x₁ , y₁) and (x₂, y₂)
4. Substitute x₁ , y₁, x₂, and y₂ into the formula
5. Solve
Slope of (0,2) and (-8,-8):
Point 1: (0,2) x₁ = 0 y₁ = 2
Point 2: (-8,-8) x₂ = -8 y₂ = -8
Formula for slope
Substituted points
Simplified the subtraction then the negatives
Reduce fraction by dividing top and bottom by 2
First slope
Slope of (-8,-5) and (8,15):
Point 1: (-8,-5) x₁ = -8 y₁ = -5
Point 2: (8,15) x₂ = 8 y₂ = 15
Formula for slope
Substituted points
Simplified the subtraction into addition
Reduce fraction (divide top and bottom by 4)
Second slope
Answer:
The sum of interior angles of given polygon is 900°
Step-by-step explanation:
A regular polygon is a n-sided figure with n sides and the length of all sides is same.
In the diagram, we have a polygon with 7 sides.
The formula given is used to calculate the sum of interior angles of a polygon
Here n is the number of sides of polygon
In the given polygon
n = 7
So,
Hence,
The sum of interior angles of given polygon is 900°
