Question

in the figure below, m∠1 = 66° and m∠2 = 78°. find m∠jkm.

Explanation:

Step1: Identify angle - addition relationship

$\angle JKM=\angle1 + \angle2$

Step2: Substitute given angle measures

$m\angle JKM=66^{\circ}+78^{\circ}$

Step3: Calculate the sum

$m\angle JKM = 144^{\circ}$

Answer:

$144$
