Answer:

122

Step-by-step explanation:

Angles of a quadrilateral add up to 360 then let the angle with x be y

So

119+78+105+y=360

302+y=360

y=360-302

y=58

Now

x+y=180 (angles on a straight line)

x+58=180

x=180-58

x=122

Give an example of where you would use either the Commutative or Associative Property of Addition in a real world situation.
umka2103 [35]

So the best I could come up with is paper-rock-scissors; the operation takes two inputs and puts out the winner (assuming they are different).

So (paper rock) scissors= paper scissors = scissors,

But paper (rock scissors)= paper rock = paper.

This is a good example because it shows that associativity matters even outside of math.
