The required value of Arc BC m = 140° Option B is correct.
Given that,
AD is the diameter of the circle,
∠1 = ∠3 = 20°
Arc BC is to be determined.
<h3>What is an arc?</h3>
Arc is the measure of angle on the circumference of circle.
Here,
∠1 = arc AB
∠3 = arc CD
Now, for circle p
Since angle 1 and angle 2 are equal to the composition of the arc,
Arc AD = Arc AB + Arc BC + Arc CD = 180
20 + Arc BC + 20 = 180
Arc BC = 180 - 40
Arc BC = 140°
Thus, the required value of Arc BC m = 140° Option B is correct.

Determine the probability of Bronze medal
In probability, sum is always equal to 1
i.e.
Make Bronze the subject
Substitute values for Gold and Silver
Take LCM
Hence:
The probability of picking bronze is
To find the LCM, you CAN divide the product of the two numbers by the GCF.
This is not a very well-known fact, but it is useful at times, especially when we are asked to calculate both the LCM and GCF.
For example, the GCF of 18 and 48 is 6, by inspection or by factors.
Therefore the LCM of 18 and 48 is 18*48/6=864/6=144.
It works because by definition the GCF is the products of all common factors between the two given numbers. Dividing the product by the GCF will therefore remove the duplication of the common factors, leaving a number which contains the factors of each of the two numbers, thus a lowest common multiple.
Note that this method is not the only way to find LCM's.
