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$

At the local nursery, 1/6 of the plants for sale are flowers and another 7/12 of them are bushes. What fraction of the plants fo

Irina18 [472]

Answer:

3/12

Step-by-step explanation:

Because first off, you have to make 1/6 addable to 7/12. So multiply 1/6 by 2 and should get 2/12. Add the two together (2/12 + 7/12 = 9/12). Now, How much more needs to be added to make 12/12, 3/12. So I believe the answer is 3/12.
