0%
none of these
Explanation
At $$4:15$$, the hour will be between $$4$$ and $$5$$.
And minute hand will be on $$3$$.
Thus, the angle formed between these two hands will be less than $$90^{o}$$.
Hence, they form a acute angle.

Parallelogram
Explanation
A regular polygon is one that has all sides of equal length and has equal angles between each edge of the polygon.
Between a square, a trapezium, a rectangle, and a parallelogram, the polygon that has $$4$$ equal sides is a square.
Hence square is the regular polygon of $$4$$ sides.

Explanation
Sum of the angles forming a linear pair is $$180^\circ$$
Here angles measuring $$40^\circ, 4x$$ and $$3x$$ form a linear pair.
So, $$40^\circ+4x+3x=180^\circ$$
$$7x+40^\circ=180^\circ$$
$$x=20^\circ$$

$$\angle ABC$$ in the following figure is a / an:
Report Question
0%
acute angle
0%
obtuse angle
0%
reflex angle
0%
straight angle
Explanation
Angles
larger than a straight
angle
but less than complete angle (i.e. between $$180^o$$ and $$360^o$$) are called
reflex angles.
Here, the given $$\angle ABC$$ measures
greater than $$180^o$$ but less than $$360^o$$.
Hence, the given angle is a reflex angle.
Therefore, option $$C$$ is correct.
The number of sides of a regular polygon, if each of its interior angles is $$135^{\circ}$$, is given by:

$$10$$
Explanation
Angle of a regular polygon is given by: $$\cfrac{n-2}{n}\times 180=135$$ where $$n$$ is the number of sides of the polygon
Therefore, $$180n - 360 = 135n$$
$$n =8$$ sides

What is the angle formed between the two hands of a clock at the time $$3:00?$$
Report Question
0%
Right
0%
Acute
0%
Obtuse
0%
Left
Explanation
First, note that a clock is a circle made of $$360$$ degrees and that each number represents an angle and the separation between them is $$360/12 = 30$$. And at $$3:00,$$ the minute hand is on the $$12$$ and the hour hand is on the $$3.$$
The correct answer is $$3 * 30 = 90$$ degrees.
At $$3$$ o' clock the angle formed between the two hands of a clock is $$right \ angled$$.
Hence the correct answer is option $$A$$.
