Hey!
--------------------------------
Polygon: Heptagon
Vertices: 7
Sum of angles: 900°
--------------------------------
Solution:
158 + 120 + 139 + 121 + 125 + 126 = 789
900 - 789 = 111°
--------------------------------
Answer:
x = 111°

Hope This Helped! Good Luck!
Hey!
To solve this equation, we'd first have to apply the distributing rule to this equation.
<em>Original Equation :</em>

<em>New Equation {Changed by Applying the Distribution Rule} :</em>

· 3a · 2 +

And now we simplify.
<em>Old Equation :</em>

· 3a · 2 +

<em>New Equation {Old Equation Simplified} :</em>

- 12a + 4
<em>So, the equation

simplified is</em>
- 12a + 4.Hope this helps!

Answer:
2/15
Step-by-step explanation:
2/3 divided 5 is really just:
2/3*1/5
that is just 2/15!
Answer:
25%
Step-by-step explanation:
let length of 1st square be x and second be y
then
A/q
x = y/2
area of first square = x^2 = (y/2)^2 = (y^2)/4
and
area of second square = y^ 2
so from sbove two lines
area of first square = 1/4 * area of second square
= 1/4 *100%
so..
area of first sqare = 25% of area of second square
Been a while but I'm gonna try..! Okay!
For the Focus use the vertex to find it. (9/2 , 0)
For the directrix I believe it is. x = -9/2
