Step-by-step explanation:

(i)

m <em>L</em><em> </em>BOC = 2× m <em>L</em><em> </em>BAC = 2×56 = 112°

m <em>L</em><em> </em>BCA = m <em>L</em><em> </em>BAT = 75°

m <em>L</em><em> </em>OCB = (180°-112°)/2 = 68°/2 = 34°

so, m <em>L</em><em> </em>OCA = 75°-34° = 41°

The answer is A.

Step-by-step explanation:

Calculate the pay for the following day of a weekly time card given a wage of $14/hr
xxTIMURxx [149]

Answer: $122.50

Step-by-step explanation:

We know the difference between the time the employee clocked in and clocked out = 1200 - 0800 = 4 hours

The next clock in and out = 17:30 - 12:45 = 4 hours, 45 minutes.

These times combined = 8 hours, 45 minutes

\frac{45}{60} minutes in an hour = \frac{3}{4} of an hour.

The total time worked was 8 \frac{3}{4} hours.

Multiply 8.75 × $14 = $122.50

I am not a professional, simply using prior knowledge.

Note- it would mean the world to me if you could mark me brainliest!
