Answer:
(b) 36 degrees.
Step-by-step explanation:
K is the center of the circle so triangle KMN is isosceles and m < KMN = m KNM = 26 degrees ( base angles are equal)
So m < LMK = m <LMN - m < KMN
= 98 - 26
= 72 degrees.
Now triangle LKM is also isosceles since K is the center of the circle so
m < LKM = 180 - 2* 72
= 180 - 144
= 36 degrees.
