Answer:CR= 53
AB = 118
CAB = 236
Step-by-step explanation: a whole is circle is equal to 360 degrees and when you see the two parts which dint have an angle, they look the same size. So I pluses 53 and 71 than subtracted from 360. Which then I divided it by two then you get the angle for A to B.
Hope this helped and hope this is the correct answer.
Yes the left states your reasoning
Its 1400 divided by 224 so it will be 6.25 times
KE=0.5xmxv2
=0.5x 1.2x10^3x (3.4x10^3)^2=6936000000
