The first property is commutative  ( the numbers 38 and 677 are  swapped over)



Then we have the associative property ( where the paretheses are moved to get 38 and -38 together)

then the additive inverse ( 38 + (-38) = 0

and finally to get the 677 we use the additive identity property.

What is the value of x, y, and z?
deff fn [24]

Answer:  x = 34º,  y = 146º,  z = 146º

Step-by-step explanation:

Adding the angles inside a triangle gives you 180º. So

85 + 61 + x = 180

146 + x = 180

x = 34º

x and y are supplementary, so y = 180 - x = 180 - 34 = 146º.

y and z are equal (vertical angles), so z = 146º.
