68. add the two measures then subtract from 180.
Answer:
increase
Step-by-step explanation:
5kg to 5212g

1kg=1000g, so
5kg=5000g
And 5000g<5212g
Therefore, it is an increase

Say r is rational. Suppose for a second, that s is not. Then, r+s is irrational. But this contradicts the fact that b is rational.
So, if one root is rational, then the other root is also rational
