Answer:
In the commutative property, order does not matter. However, this is not true when it comes to substraction & division problems where order does matter.
Step-by-step explanation:
Commutative property states that there is no change in result when the numbers in an expression are reversed. Commutative property is true for addition and multiplication but not for subtraction and division.
Answer:
Angle ABD = 60
Step-by-step explanation:
Angle ABD = angle ABC + angle CBD
We are given that angle ABC = 25 and angle CBD = 35
So angle ABD = 25 + 35 = 60
