Question

What is m∠BKD 43 23 20 63

Answer 1

Answer: Fourth option is correct.

Step-by-step 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,

$m\angle BKD=\dfrac{AE+BD}{2}\\\\m\angle BKD=\dfrac{86+40}{2}\\\\m\angle BKD=\dfrac{126}{2}\\\\m\angle BKD=63^\circ$

Hence, ∠BKD = 63°

Therefore, Fourth option is correct.
