5 - How many commonly used measurements for angles?
- 1 - 3
- 2 - 2
- 3 - 5
- 4 - 4
- Answer Description :
4 There are four commonly used measurements for angles: Degrees (°) Radians (rad) Gradians (grad or gon) Turns (revolutions or cycles)

6 - Length of side of suquare is 2cm. find its Perimeter
- 1 - 4
- 2 - 6
- 3 - 8
- 4 - 12
- Answer Description :
8 The perimeter of a square is calculated by adding the lengths of all its sides. Since each side of the square is 2 cm, the perimeter will be equal to 4 times the length of one side, which is 4 * 2 cm = 8 cm. Therefore, the correct answer is c. 8.

7 - The largest and smallest values of any given class of frequency distribution are called:
- 1 - Class limits
- 2 - Class interval
- 3 - Class marks
- 4 - Class boundaries
- Answer Description :
Class limits The largest and smallest values of any given class of frequency distribution are called class limits. They define the boundaries of each class interval and represent the minimum and maximum values included in that class.

8 - Sets with the same number of members are ________________.
- 1 - Empty sets
- 2 - Parallel sets
- 3 - Equivalent sets
- 4 - None
- Answer Description :
-
9 - Convert 2π/3 radian into degree
- 1 - 60°
- 2 - 40°
- 3 - 100°
- 4 - 120°
- Answer Description :
120° To convert radians to degrees, we use the conversion factor where 180° is equivalent to π radians. Given 2π/3 radians, we can calculate the degree equivalent as follows: Degree Equivalent = (2π/3) * (180°/π) = (2 * 180°) / 3 = 360° / 3 = 120° Therefore, the correct answer is d. 120°.

10 - Sum of angles 150 and 30 is known as
- 1 - Supplementary angle
- 2 - Complementary angle
- 3 - Straight angle
- 4 - Obtuse angle
- Answer Description :
Straight angle The sum of angles 150° and 30° is known as a straight angle. A straight angle measures exactly 180°, and when two angles add up to 180°, they form a straight angle.
