Mathematics for IGCSE & O level - Pythagoras' Theorem And Trigonometry (Section 6 - No. 14)

If the angle of elevation of the sun is 30 degrees, and a tree casts a shadow of 10 meters, what is the height of the tree (approximately)?

5 m

5.77 m

10 m

17.32 m

Use tan(30) = height/10, height = 10 * tan(30) ≈ 5.77 meters. However the question incorrectly states the height.
