Triangle J K L is shown. Angle J K L is 120 degrees and angle K L J is 40 degrees. The length of K L is 2 and the length of J L

Veseljchak [2.6K]

Answer:

$k \approx 5$ units$

Step-by-step explanation:

In Triangle JKL

$\angle K=120^\circ\\\angle L=40^\circ\\KL=2\\JL=k$

We want to determine the approximate value of k using the law of sines.

$\angle J+\angle K+\angle L=180^\circ $ (Sum of angles in a \triangle)\\\angle J+120^\circ+40^\circ=180^\circ \\\angle J=180^\circ-(120^\circ+40^\circ)=20^\circ$

Using Law of Sines

$\dfrac{k}{\sin K} =\dfrac{j}{\sin J} \\\dfrac{k}{\sin 120} =\dfrac{2}{\sin 20} \\k=\sin 120 \times \dfrac{2}{\sin 20}\\k=5.06\\k \approx 5$ units$

A central angle measuring 120° intercepts an arc in a circle whose radius is 3.

Kisachek [45]

Answer:

6.28

Step-by-step explanation:

The length of arc which subtends an angle $\alpha$ at the center of a circle is given by $\alpha r$ where r is the radius of circle.

______________________________

given

the central angle of arc is 120°

$\pi = 180\\120 = (\pi /180)* 120\\120 = 2/3\pi$

we will use value of $\pi$ as 3.14

r = 3

Length of this arc is

$2/3( \pi *3) = 2\pi \\=2*3.14 = 6.28$

The length of the arc to the nearest hundredth of unit is 6.28
