Answer:
x ≈ 5.2
Step-by-step explanation:
using the tangent ratio in the right triangle
tan74° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{18}{x}[/tex] ( multiply both sides by x )
x × tan74° = 18 ( divide both sides by tan74° )
x = [tex]\frac{18}{tan74}[/tex] ≈ 5.2 ( to the nearest tenth )
