Question

Given LN is perpendicular to KN, LN=16 feet m

Answer 1

Answer:

Without seeing the real diagram, there are two interpretation:

• KM is a diameter. But that can't be or else m∠L = 90°.
• KM is a chord. We know m∠L = 100°

Triangle LNM is tight-angled and tan 55° = 16/NM

• NM = 16/ tan 55° = 11.20332...

In the same way, find KN

We now have the chord KM,

Let the radius be R

• The angle subtended by a chord at the centre is twice the angle at the circle.

So angle KOM = 200°

By the cosine law

• R² + R² - 2(R)(R)cos 200° = KM²
• R = 19.39057726m.
