m<CAD= 23 degrees

m<CAB= 67 degrees

Step-by-step explanation:

From the diagram shown;

arc ADC + arc CAB = 360

226 + arcCAB = 360

arc CAB = 360 - 226

arc CAB  = 134

Also arcCD = 226 - 180

arcCD = 46degrees

Since <A = 1/2arcCD

m<CAD = 1/2* 46

m<CAD= 23 degrees

m<CAB = 90 - <A

m<CAB = 90 - 23

m<CAB = 67degrees

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
