Question 1 · 1 mark · Difficulty 1/3

What is the exact value of sin 30°?

  1. √3/2
  2. 1/2
  3. √2/2
  4. 1/√3
Show answer & explanation
✓ Answer: B1/2
Award 1 mark for recalling the exact value of sin 30° = 1/2. A is incorrect — this is the value of cos 30° or sin 60°. C is incorrect — this is sin 45°. D is incorrect — this is tan 30°.
Question 2 · 1 mark · Difficulty 2/3

A surveyor in Trinidad is measuring the height of a coconut palm tree. From a point 12 metres away from the base of the tree, the angle of elevation to the top of the tree is 40°. Which expression correctly gives the height of the tree?

  1. 12 × sin 40°
  2. 12 × cos 40°
  3. 12 × tan 40°
  4. 12 ÷ tan 40°
Show answer & explanation
✓ Answer: C12 × tan 40°
Award 1 mark for recognising that tan θ = opposite/adjacent, so height = 12 × tan 40°. A is incorrect because sin 40° requires the hypotenuse. B is incorrect because cos 40° would give the adjacent side when the hypotenuse is known. D is incorrect as it inverts the relationship.
