Which statement is an example of the transitive property of congruence?

a. if , then .
b. if , then .
c.
d. if and , then .

D. If  and , then is an example of transitive property of congruence.

Step-by-step explanation:

Transitive property of congruenc: If one segment is congruent to second segment and second is congruent to third segment then the segment one is congruent to third segment.

For example: If

and

Then

Therefore we can see in angles

If

And

Then

Therefore, the statement of transitive property written as

If and, then

Hence, If and,  then is an example of the transitive property of congruence.

answer: 60

step-by-step explanation:

1/2a + (2/3×30)   = 50

1/2a + 20 = 50

1/2a = 30

a = 60

the answer is 4.8 units on e2020.
