Answer:
B=100
Step-by-step explanation:
The given circle is
Consider the triangle AOB, Using the triangle sum property, we get
AOB+AOB+BOA=180
Substitute ABO=55 and BAO=45 we get
AOB+55+45=180
AOB+100=180
AOB+100-100=180-100
AOB=80
Here AOB and AOC are supplementary angles
The sum of the supplementary angles is 180 degrees.
AOB+AOC=180
Substitute AOB=80 we get
80+AOC=180
80+ AOC-80=180-80
AOC=100
Now consider the Central angle AOC and intercepted arc AC.
mAOC=mAC
Substitute m AOC=100 and mAC=b we get
100=b
Hence the value of b is 100 degrees.
Answer:
H and J are not true
Step-by-step explanation:
H) 12/65 ≠ 55/300
J) 11/65 ≠ 60/400
T+6=24. The value the bakes the equation true is 18. To find this, you would subtract 6 from 24, which would be 18. If you add 6 marbles to 18 marbles, that would be 24, therefor, Tim would have 18 marbles, making Nirja have 24 marbles. I'm 100% this is true. Hope this helps! Please mark brainiest! :)
