Answer:
18.2
Step-by-step explanation:
JK is the side perpendicular to the horizontal (JL) thus it is opposite to angle 55°. JL is the adjacent, therefore, we can use the trigonometric ratio Tangent to fins the adjacent.
Tan ∅= opposite/ adjacent
Adjacent = opposite/Tan ∅
Adjacent =26/ Tan 55°
=18.2
