Answer 1

find the measure of angle a

Answer 2

What is the total if you add up the angles of that shape?
For example if you add up all the angles for a triangle you get 180

Answer 3

well i used the formula (n-2)360

Answer 4

is that wrong

Answer 5

can you walk me step by step through the problem

Answer 6

A+B+C+D+E+F+G=?
Where ? is the total angle.
I told you to find that total for that shape. If you don't know what it is look it up

Answer 7

wait im confused

Answer 8

A B C D E F G are the angle given.
Im telling you to add them up together and that summation will equal the total angle.

I told you for the 3rd time to look that up

Answer 9

they add up to 36x+504

Answer 10

a step by step walk through would help

Answer 11

Well you got most of it
36x+504=?

Answer 12

Do you know what ? is

Answer 13

no i dont

Answer 14

360?

Answer 15

No 900

Answer 16

a triangle adds up to 180
a square adds up to 360

Answer 17

The figure is a 7-gon (also known a heptagon or septagon). The sum of its interior angles is (7-2)* 180 = 900.
So, 36x+504 = 900
and
x = 11
Angle A = 9x - 2
Angle A = 9*11 - 2
Angle A = 99 - 2 = 97 --> Answer

Answer 18

and so on but I don't really know by how much the angle total increases but for a 7 shape add up to 900
