The convex heptagon has 14 distinct diagonals can be drawn
Step-by-step explanation:
A polygon is said to be a heptagon if it has 7 vertices, 7 sides and 7 angles. A heptagon is called a convex heptagon if the lines connecting any two non-adjacent vertices lie completely inside the heptagon
The formula of number of diagonals in any polygon is
, where
- d is the number of the diagonals of the polygon
- n is the number of sides of the polygon
∵ The heptagon has 7 sides
∴ n = 7
∵ The number of diagonals =
- Substitute n by 7 in the rule above
∴ The number of diagonals = 
∴ The number of diagonals = 
∴ The number of diagonals = 
∴ The number of diagonals = 14

Answer:
x + y ≥ 20
3x + 5y > 60
Step-by-step explanation:
Let
Bags of candy corn = x
Bags of chocolate = y
Cost of bags of candy corn = $3
Cost of bags of chocolate = $5
He needs to buy at least 20 bags of candy and he cannot spend more than $60
system of linear inequalities to model the situation.
x + y ≥ 20
3x + 5y > 60
The system ot inequalities which models the situation
x + y ≥ 20
3x + 5y > 60
Answer:
x + (x-42.2) = 90
2x - 42.2 = 90
add 42.2 to both sides
2x = 132.2
divide each side by 2
x = 66.1
find the measure of the other angle
66.1 - 42.2 = 23.9
