Step-by-Step Solution
The two acute angles add to 90°, so in the ratio 2 : 1 they are 60° and 30°. The larger is 60° and sin60° = √3/2 ≈ 0.866. Reading off the smaller angle instead gives 1/2.
Answer: A) √3/2
In a right triangle the two acute angles are in the ratio 2 : 1. The sine of the larger acute angle is:

If x = cosecθ + cotθ, then (x² − 1)/(x² + 1) equals:If tan(A + B) = √3 and tan(A − B) = 1/√3, where 0° < A + B ≤ 90° and A > B, then:The product (1 + cotθ − cosecθ)(1 + tanθ + secθ) simplifies to:If sinθ = 1/3, then the value of sin3θ is:If cosθ = −3/5 and θ lies in the third quadrant, then tanθ equals:
