Answer:
∠KNC and ∠KMC are right angles
∠MCN = 25°
Step-by-step explanation:
if KM and KN are tangent lines, then they are perpendicular to the radius going through the tangent point, so therefore right angles are:
1. ∠KNC
2. ∠KMC
the outside angle of a circle is equivalent to half the measure of the intercepted arc, so
if ∠MKN = 50°, then ∠MCN = 25°
