Plz helpp what is b?

41 degrees

Step-by-step explanation:

the two squares that make up the rhombus are both equilateral so we know that the measure of angle WUX is 56 degrees. subtract 15 from 56 and you get 41 degrees.

Step-by-step explanation:

Part A: 0.85 + 0.5 + 0.15 - 0.3

Part B:

Commutative Property 0.85 + 0.15 + 0.5 - 0.3

Associative Property  (0.85 + 0.15) + (0.5 - 0.3)

1 + 0.2 = 1.2 liter of mixture left
