Answer:
m<AOC=60
m<BOC=30
Step-by-step explanation:
First you can substitute "x" for both the angles getting that "x=x+30". Then you can set that equation equal to 90 getting "x+x+30=90". Finally after simplifying you will end up with "2x=60". Making "x=30", Then we know that m∠AOC = m∠BOC +30°, so m∠AOC= 30+30, which means that m∠AOC=60 and m∠BOC=30.
