Option D:
The length of LJ = 3.5
Solution:
In the triangle LJK,
LK = 9, ∠K = 23°, ∠J = 89°
To find the length of LJ:
<u>Law of sine: </u>
A, B, C are the angles of the triangle and
a, b, c are the sides of the triangle.
Here for ΔLJK,
The side opposite to angle L is <em>l</em>.
The side opposite to angle J is <em>j</em>.
The side opposite to angle K is <em>k</em>.
Take only two sides.
LJ = 3.5 (approximately)
Option D is the correct answer.
The length of LJ = 3.5.
