Hmm, I believe a 5-sided shape has a total of 540 degrees, you could subtract all the values you have already to find the x degree.
OpenStudy (danjs):
You remember how the sum of interior angles of polygons add up
OpenStudy (danjs):
A triangle has 180 degrees, each addition of another side to that will add 180 more for each side...
OpenStudy (narissa):
Yeah i think so. 180(5)

180(5-2) = 180(3) = 540.
OpenStudy (danjs):
The number of sides, say n, will have interior angles sum to
(n - 2)*180
OpenStudy (vuriffy):
180(n-2) is the formula.
OpenStudy (narissa):
ah okay now i see where i messed up i kept getting 900 degrees
OpenStudy (vuriffy):
90+107+144+138 = 479.
You may subtract 540 - 479 = x
Your remaining degree which totals up the degrees to 540.

x=90 degrees okay thanks @Vuriffy and @DanJS
OpenStudy (vuriffy):
@narissa No, slow down.
OpenStudy (vuriffy):
The 90 degrees comes from the right angle, as you see in the shape, correct?
OpenStudy (narissa):
yes
OpenStudy (vuriffy):
x is a different value.

151?
OpenStudy (vuriffy):
All you have to do now is add of the other degrees which you get 479.
The total is 540.
540 - 479 = x
OpenStudy (narissa):
oh 61
OpenStudy (vuriffy):
Yes, x = 61. Good job!
OpenStudy (narissa):
Thank you i need to write this down lol
