Answer 2

Find "x" first.

Answer 3

how?

Answer 4

using 49

Answer 5

would i add all the angles and equal them to 360?

Answer 6

yes. then solve for x and then you can easily solve for angle A

Answer 7

okay ill try . is it equal to 360 or would it be 540

Answer 8

Sum Of interior Angles + Exterior angles = 5(180)
Write this expression in terms of x and solve for x.

Answer 9

that made no sence

Answer 10

What made no sense.

Answer 11

use 360

Answer 12

okay i got x = 10 , now what do i do

Answer 13

the figure says angle A=6x-3

Answer 14

oh okay i wasnt sure if that was it

Answer 15

3 (180) + 6 x - 3 + 14 x + 6 + 3 x + 30 + 49 + 4 x + 8 = 5 (180)

x=10

Answer 16

Notice that 5(180)- 3(180) = 360
So we are talking the same things and it does make sense.
