MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Convert the angle θ = 135° from degrees to radian measure or radians to degrees, whichever is appropriate. Fill in the blank with the correct answer.

θ = 3π/4

θ = 5π/6

θ = 2π/3

θ = π/2

Answer explanation

To convert 135° to radians, use the formula: radians = degrees × (π/180). Thus, 135° × (π/180) = 3π/4. Therefore, the correct answer is θ = 3π/4.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Convert the angle θ = 240° from degrees to radian measure or radians to degrees, whichever is appropriate. Fill in the blank with the correct answer.

θ = 4π/3

θ = 2π/3

θ = 3π/2

θ = π/2

Answer explanation

To convert 240° to radians, use the formula: radians = degrees × (π/180). Thus, 240° × (π/180) = 4π/3. Therefore, the correct answer is θ = 4π/3.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Convert the angle θ = 7π/5 from degrees to radian measure or radians to degrees, whichever is appropriate. Fill in the blank with the correct answer.

θ = 252°

θ = 180°

θ = 315°

θ = 210°

Answer explanation

To convert radians to degrees, use the formula: degrees = radians × (180/π). For θ = 7π/5, it becomes 7π/5 × (180/π) = 252°. Thus, the correct answer is θ = 252°.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Convert the angle θ = 11π/12 from degrees to radian measure or radians to degrees, whichever is appropriate. Fill in the blank with the correct answer.

θ = 165°

θ = 150°

θ = 120°

θ = 180°

Answer explanation

To convert radians to degrees, use the formula: degrees = radians × (180/π). For θ = 11π/12, it becomes 11π/12 × (180/π) = 165°. Thus, the correct answer is θ = 165°.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Convert the angle θ = 330° from degrees to radian measure or radians to degrees, whichever is appropriate. Fill in the blank with the correct answer.

θ = 11π/6

θ = 5π/6

θ = 7π/4

θ = 2π/3

Answer explanation

To convert 330° to radians, use the formula θ (radians) = θ (degrees) × π/180. Thus, 330° × π/180 = 11π/6. Therefore, the correct answer is θ = 11π/6.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Convert the angle θ = 270° from degrees to radian measure or radians to degrees, whichever is appropriate. Fill in the blank with the correct answer.

θ = 3π/2

θ = π/2

θ = π

θ = 2π

Answer explanation

To convert 270° to radians, use the formula: radians = degrees × (π/180). Thus, 270° × (π/180) = 3π/2. Therefore, the correct answer is θ = 3π/2.

MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Convert the angle θ = 15π/8 from degrees to radian measure or radians to degrees, whichever is appropriate. Fill in the blank with the correct answer.

θ = 337.5°

θ = 225°

θ = 315°

θ = 270°

Answer explanation

To convert θ = 15π/8 radians to degrees, use the formula: degrees = radians × (180/π). Thus, θ = (15π/8) × (180/π) = 337.5°. Therefore, the correct answer is θ = 337.5°.
