Answer:
93.39
Step-by-step explanation:
So the sum of exterior angles of the convex octagon is: 360 degrees
This means if we add all the equations that represent each angle, we can set it equal to 360 and solve for x

Group like terms

Add like terms

Now let's set the sum of exterior angles to 360

Subtract 2 from both sides

Divide both sides by 23

So by looking at all these, it appears that 6x is the highest value, given that x is positive. The way I estimated, is approximately 15.5, whenever I saw an equation like x+14, I estimated it's about 2x, since 14 is not exactly, but close to 15.5. I did this with each polynomial given. You could also manually check each one
Original equation
6x

Answer:
26
Step-by-step explanation:
The sum of angles in a triangle is 180 degrees, use this and set up an equation;
x + ( 4x -5 ) + 55 = 180
Simplify
x + ( 4x - 5 ) + 55 = 180
5x + 50 = 180
Inverse operations;
5x + 50 = 180
-50 - 50
5x = 130
/5 /5
x = 26
The fourth graph or D (the one in the bottom right corner) this is because a pyramid consists of four triangles and one square at the bottom.

Answer:
Step-by-step explanation:
-16-16v - v = 10v + 4
Add 16 to both sides and combine like terms giving you
15v = 10v + 20
Subtract 10v from both sides
5v= 20
Divide by 5
V=4
