I need help with this (giving brainliest)

R=110 degrees

B=110 degrees

Step-by-step explanation:

R and B are the same angle, we minused the mesure of G and since angle O is same as the other angle we multiplied 60 by two and then added 20 which gave us 140

360-140=R+B

220=R=B

110=R

110=B

m<R = 120 degrees, m<B = 100 degrees

Step-by-step explanation:

1. i found the blue line and the angle of any line is 180 degrees

2. since angle O is 60 you have to subtract it from 180 -60 = 120 = m<R.

3. this one is more complicated you have to subtract angle O and angle G which is 20 degrees so you add 20 + 60 = 80 and then you take the sum and subtract it from 180: 180 - 80 = 100

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

hope to and hope that my answer is brainliest.(follow me )
