  1. In a 30-60-90 triangle, the shortest leg has length 5. What is the length of the hypotenuse?

    Answer: 10

    In a 30-60-90 triangle, the hypotenuse is twice the length of the shortest leg, so it is 2 × 5 = 10.

  2. In a 45-45-90 triangle, one leg has length 7. What is the length of the hypotenuse?

    Answer: 7√2

    In a 45-45-90 triangle, the hypotenuse = leg × √2 = 7√2.

  3. What is the surface area of a cube with side length 4?

    Answer: 96

    A cube has 6 faces, each with area 4² = 16, so surface area = 6 × 16 = 96.

  4. A sector of a circle has a central angle of 90° and radius 8. What is the arc length? (Use π ≈ 3.14)

    Answer: 12.56

    Arc length = (θ/360°) × 2πr = (90/360) × 2 × 3.14 × 8 = (1/4) × 50.24 = 12.56.

  5. Two parallel lines are cut by a transversal. One pair of alternate interior angles measures (3x + 10)° and (5x − 20)°. What is x?

    Answer: 15

    Alternate interior angles are equal: 3x + 10 = 5x − 20, so 30 = 2x, giving x = 15.

  6. What is the volume of a cylinder with radius 3 and height 5? (Use π ≈ 3.14)

    Answer: 141.3

    Volume = πr²h = 3.14 × 9 × 5 = 141.3.

  7. A line passes through the origin with slope 2. Which equation represents this line?

    Answer: y = 2x

    A line through the origin has a y-intercept of 0, so the equation is y = 2x.
