Answer:
m∠KOL = 30°
Step-by-step explanation:
It is given that mKL = 90and mMN = 30∘.
If two secants intersect in the exterior of a circle, then the measure of the angle formed is half the difference of the measures of its intercepted arcs. So,
m∠KOL= 1/2(mKL− mMN)
Substitute the given values and simplify.
m∠KOL= 1/2 (90∘−30∘)
= 1/2(60∘)
= 30∘
Therefor, m∠KOL=30∘.
