Because OP and OR trisect <NOS
so <NOP = <POR
3x - 4y = x - y so 2x = 3y
<POR = <ROS
x - y = y - 10 so x = 2y - 10
Substitue x = 2y - 10 into 2x = 3y
2(2y - 10) = 3y
4y - 20 = 3y
y = 20
x = 2y - 10 = 2(20) - 10 = 30
x = 30 and y = 20
<ROS = y - 10 = 20 - 10 = 10
Answer
<ROS = 10°
The chord 3cm away is 12cm and chord 6cm away is 6cm.

Answer:
answer 13.33333 hours h
Step-by-step explanation:
Julia studied 3 1/3 hours during 4 days
this means she studied:
3 1/3 of 4 days of 24 hours
3 1/3 = 9/3 x 1/3 = 10/3
and 4 days of 24 hours is 4 x 24 = 96
there for
10/3 x 96 = (10/1)x32 =320 hours
320/24 hours each day -13.3333
