GCSE Maths – Trigonometry Question (Q10) Solution A right-angled triangle has a hypotenuse of
15 cm. The opposite side to angle θ is 8.9 cm. We use the sine ratio: sin(θ) = opposite / hypotenuse
= 8. sin(θ) = 0.593333... θ = arcsin(0.593333...) θ ≈ 36.4° Final Answer: θ = 36.4° (to 1
decimal place)
