If 10 + a = 10, then a = 0

which property is demonstrated by the example?
a) substitution
b) identity property for addition
c) multiplicative property of zero
d) inverse property for multiplication

B) identity property of addition.

Step-by-step explanation:

Given:

The statement given is:

Here, we observe that 10 is added to a giving the number 10 itself as the answer. So, we know of a property which says that when 0 is added to a number, the result is the number itself. This property is called identity property of addition.

So, the value of must be 0 because on adding to 10, we are getting the number 10 only. So, the above statement is an example of identity property of addition.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
