Find: KM ...... .. . .. .

Question

Given: ∆KLM, KL = LM m∠K = 17°, R = 1.08 Find: KM

Answer 1

Draw 3 radii to the points K, L, & M.

The angle at L is 146° and half of it is 73°

KL=ML

KL/2 =1.08*sin 73 since 73 is the base angle of an isosceles triangle

(KL/2)/(KM/2)=cos 17 in the right triangle

KM=KL/cos 17

I will leave the numerical work to you.
