Question

What is m∠BKD

43

23

20

63

Answer 1

check the picture below.

Answer 2

Answer: Fourth option is correct.

Explanation:

Since we have given that

Measure of AE = 86

Measure of BD = 40

We need to find the measure of ∠BKD.

Since we know that the central angle is the average of measures of two intercepted arc of this angle.

So, it becomes,

`m\angle BKD=(AE+BD)/(2)\\\\m\angle BKD=(86+40)/(2)\\\\m\angle BKD=(126)/(2)\\\\m\angle BKD=63^\circ`

Hence, ∠BKD = 63°

Therefore, Fourth option is correct.
