Question

What are the missing measures

Answer 1

How many sides does the polygon have?

Answer 2

6...

Answer 3

good
What is the sum of the measures of all the angles of a polygon?
Do you know the formula?

Answer 4

517? and no i do not no the formula

Answer 5

The formula is:
The sum of the measure of the angles of a polynomial of n sides is
(n - 2)*180
Just subtract 2 from the number of sides and multiply by 180
Your polynomial has 6 sides, can you find the sum of the measures of the angles?

Answer 6

im confused.?

Answer 7

Take the number of sides, 6
Subtract 2 from it. What do you get?

Answer 8

4?

Answer 9

good
Now multiply 4 by 180. What do you get?

Answer 10

720

Answer 11

great.
Now you know that the measures of all those angles in your figure added up equal 720.

Answer 12

You add up all the measures given in the figure and set it equal to the sum you got from the formula:
4x + 135 + 120 + 125 + 3x + 130 = 720

Answer 13

Now you need to solve the equation for x.

Answer 14

how do you solve for X?

Answer 15

Add 4x and 3x on the left side
Add all the numbers on the left side

Answer 16

What is 4x + 3x = ?

Answer 17

What is 135 + 120 + 125 + 130 = ?

Answer 18

4x+3x=7x
and 135+120+125+130=510

Answer 19

Great, so you have:
4x + 135 + 120 + 125 + 3x + 130 = 720
7x + 510 = 720
Now subtract 510 from both sides.

Answer 20

Now divide both sides by 7 to get x.
Once you have x, multiply x by 3 and by 4 to get the 2 angle measures.
