Which property is shown? if m∠abc = m∠cbd, then m∠cbd = m∠abc reflexive property substitution property symmetric property transitive property

Symmetric property tells that if Something = Another Thing, then Another Thing = Something.

So, symmetric property is at work here.

1/3 + 1/5 = 8/15.

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
