<em>The question is incomplete, as the required clocks are not given.</em>
<em>To answer this question, I will give an illustration of how to calculate the difference between times.</em>
<em>Note that: I assume you can read the time on a clock</em>
<em></em>
Assume that:

The difference is calculated as:


From 2:15pm to 3:05pm is 50 minutes.
So:

Another assumption:

The difference is calculated as:


For ease of calculation, we split the time to 2.
(1) From 2:15pm to 3:15pm
(2) From 3:15pm to 3:32pm
(1) From 2:15pm to 3:15pm: This is 1 hour
(2) From 3:15pm to 3:32pm: This is 17 minutes (i.e. 32 - 15)
So, the difference is:


Answer:
8.66
Step-by-step explanation:
b = a sqrt(3)
Answer:
Option (A)
Step-by-step explanation:
To find the value of 'a' we will use the tangent-chord theorem,
"Angle formed by the chord and a tangent to the circle measure the half of the intercepted minor arc"
Angle 'a' is formed between the chord and the tangent.
Measure of the intercepted arc = (2 × 52)°
Therefore, measure of the angle 'a' = 
a = 52°
Therefore, Option (A) will be the correct option.
