Hexagon ABCDEF is a regular hexagon. Show that segments AE and ED are perpendicular.
1 answer:
For a regular hexagon, the interior angles are 120°, since they add up to 720 (180(6 - 2))
We also know, for a regular hexagon, all sides are equal.
Refer to my diagram.
Triangle AFE is an isosceles triangle, because two sides of the triangle are equal in a regular hexagon.
Thus, 120 + 2x = 180 (angle sum of triangle)
2x = 60 and x = 30
Now, ∠FEA = 30°, but we know that ∠FED is 120° (all interior angles of a regular hexagon is 120°)
We know that ∠FED = ∠FEA + ∠AED
120° = 30° + ∠AED
∴ ∠AED = 90° (120 - 30)
If ∠AED is 90°, then, by definition, AE ⊥ ED

Answer:
we get the all equation of given condition &
Step-by-step explanation:
Given that,
Number of painting made by Gloria every month is 2.
Gloria creates depends on the number of paintings p, Gloria paints over m months if she meet her goal.
we have to check all the apply.
According to question,
M is the independent variable and P is dependent variable.
So, Relation formed by given statement is
Case(1): P is increased by 2 as M is increased by 1.
Then,
This is Equation of the given case(1).
Again, P is the independent variable and M is dependent variable.
∴
Case (2) M is increased by 2 as P increased by 1.
Then,
Hence,
we get the all equation of given condition &
