In a right triangle ABC with right angle at B, if AB = 3 cm and BC = 4 cm, what is the value of sin A?
What is the value of cos 60°?
If sin θ = 3/5, what is the value of cos θ? (θ is an acute angle)
In a right triangle, if the hypotenuse is 13 cm and one side is 5 cm, find sin θ where θ is the angle opposite to the 5 cm side.
Sample Questions
Which of the following are equal to tan 45°? (Select all correct answers)
Show answer
1, sin 45°/cos 45°, (√2/2)/(√2/2)
tan 45° = 1. Also, tan θ = sin θ/cos θ, so tan 45° = sin 45°/cos 45°. Since sin 45° = cos 45° = √2/2, we have tan 45° = (√2/2)/(√2/2) = 1.
What is the value of sin²30° + cos²30°?
Show answer
1
By the fundamental trigonometric identity, sin²θ + cos²θ = 1 for any angle θ. This is true for θ = 30° as well. We can verify: sin 30° = 1/2, cos 30° = √3/2, so sin²30° + cos²30° = (1/2)² + (√3/2)² = 1/4 + 3/4 = 1.
If cos A = 0.8, what is the value of sin A? (A is an acute angle)
Show answer
0.6
Using sin²A + cos²A = 1: sin²A + (0.8)² = 1, so sin²A + 0.64 = 1, therefore sin²A = 0.36, so sin A = 0.6 (positive since A is acute).
Which of the following statements are true? (Select all correct answers)
Show answer
sin 0° = 0, cos 90° = 0, sin 90° = 1, cos 0° = 1
From the standard values: sin 0° = 0, cos 0° = 1, sin 90° = 1, cos 90° = 0, and tan 0° = 0 (not 1).
