Which is the height of the lighthouse?

Answer:
Step-by-step explanation:
tan 26° = [tex]\frac{x}{90}[/tex] ⇒ x = 90tan26° ≈ 43.9 ft. (This answer for the picture)
sin 26° = [tex]\frac{h}{100}[/tex] ⇒ h = 100sin26° ≈ 43.9 ft (This answer for the text)
h = √(100² - 90²) ≈ 43.589 ft. (Pythagorean theorem)
