In the figure above, KL//NM, LN bisects o and angle MKN is 35o, calculate the size of angle KMN.
Attached Figure / Diagram
A
91o
B
89o
C
37o
D
19o
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
In the diagram above, \(\alpha\) = 54o(alternate angles; KL||MN) o
35o + o = 180o(sum of angles of \(\bigtriangleup\))
o = 180o
o - 143o
= 37o
