Can you me with number 6 it would be so !

∠ROQ=41.5°

Step-by-step explanation:

we know that

∠NOQ=∠NOP+∠POR+∠ROQ > equation A

∠POR=∠ROQ > equation B (given problem)

substitute equation B in equation A

∠NOQ=∠NOP+∠ROQ+∠ROQ

∠NOQ=∠NOP+2∠ROQ

we have

∠NOP=31°

∠NOQ=114°

substitute and solve for ∠ROQ

114°=31°+2∠ROQ

2∠ROQ=114°-31°

2∠ROQ=83°

∠ROQ=41.5°

there are 4 significant figures.
