Answer:

The measure of the perpendicular KD is 8.72 unit .

Step-by-step explanation:

Given as :

The triangle AKM  , with KD perpendicular to AM

The measure of side AK = 6 unit

The measure of side KM = 10 unit

The ∠ AKM = 93°

Let The measure of side KD = x unit

Now,

∵ KD ⊥ AM , KD divide the angle  ∠ AKM  equally

So,  ∠ AKD =  ∠ [tex]\dfrac{AKM}{2}[/tex]

I.e  ∠ AKD =  ∠ [tex]\{93}{2}[/tex]

∴  ∠ AKD = 46.5°

Now, Again

Cos Ф =  [tex]\dfrac{AK}{KD}[/tex]

I.e Cos 46.5° = [tex]\dfrac{6}{KD}[/tex]

I.e 0.688 = [tex]\dfrac{6}{KD}[/tex]

∴ KD = [tex]\dfrac{6}{0.688}[/tex]

I.e KD = 8.72 unit

Hence The measure of the perpendicular KD is 8.72 unit  Answer
