Question

What is the approximate value of K? Use the law of sines to find the answer.

A.) 2.9 units
B.) 3.8 units
C.) 5.1 units
D.) 6.2 units

Answer 1

its 5.1 on edg

Explanation:

Answer 2

C.) 5.1

Explanation:

First, solve for J's angle of degrees

180 - (120 + 40) = 20

Second, fill in all the information that you know in the equation

sin(20) / 2 and sin(120) / k

Third, cross multiply

k x sin(20) = 2 x sin(120)

Fourth, solve for k

k x sin(20) / sin(20) = [2 x sin(120)] / sin(20)

k = [2 x sin(120)] / sin(20)

k = 5.0641777.....

Fifth, round to the nearest tenth

k = 5.1
