Answer:
NOR = 126.6
Explanation:
one full circle would have 360 degrees
so we can make an equation that shows all of our angles adding up to 360:
NOQ + QOR + NOR = 360
we know that NOQ is 147.7
we know that QOR is 85.7
substitute these into our equation:
147.7 + 85.7 + NOR = 360
add like terms:
233.4 + NOR = 360
subtract 233.4 from both sides:
NOR = 126.6
