Explanation

$2$ right angles

$=2\times 90^o=180^o$ .

Mark the correct alternative of the following.
The number of degrees in

$3$ right angles is?

0%
$180^o$
0%
$360^o$
0%
$270^o$
0%
$90^o$

Explanation

As we know

$1$ right angle

$=90^o$ .

$3$ right angles

$=3\times 90^o=270^o$ .

Measures of the two angles between an hour and minute hands of a clock at 9'O clock are

0%
${ 60 }^{ o },{ 300 }^{ o }$
0%
${ 270 }^{ o },{ 90 }^{ o }$
0%
${ 75 }^{ o },{ 285 }^{ o }$
0%
${ 30 }^{ o },{ 300 }^{ o }$

Explanation

$\textbf {Step1: Draw a relevant figure.}$

At 9 O'clock the minute hand will be at 12 and the hour hand will be at 9 as shown in figure.

$\textbf {Step 2: Identify the angles.}$

From the above figure, we can say that the angle between hour hand and minute hand of the clock is 90,270.

$\textbf {Hence, option B is correct.}$

An angle measuring

$270^{o}$ is:

0%
an obtuse angle
0%
an acute angle
0%
a straight angle
0%
a reflex angle

Explanation

The given measure of angle is

$270^o.$

Reflex angles are angles measuring greater than

$180^o$ and less than

$360^o.$

$\therefore$

$270^o$ is a reflex angle.

Hence, option

$D$ is correct.

In figure, if point

$A$ is shifted to point

$B$ along the ray

$PX$ such that

$PB=2PA$ , then the measure of

$\angle BPY$ is

0%
Greater than ${ 45 }^{ o }$
0%
${ 45 }^{ o }$
0%
Less than ${ 45 }^{ o }$
0%
${ 90 }^{ o }$

Explanation

$\textbf {Finding the measure of the new angle.}$

From the given figure we can observe that ∠BPY and ∠APY represents the same angle formed at point P between rays PX and PY.

So, the ∠BPY will be equal to 45° as well without any change.

$\textbf {Hence, option B is correct.}$

If bicycle wheel has

$48$ spokes, then the angle between a pair of two consecutive spokes are

0%
$\left( 5\cfrac { 1 }{ 2 } \right)$
0%
$\left( 3\cfrac { 3 }{ 4 } \right)$
0%
$\left( \cfrac { 2 }{ 11 } \right)$
0%
$\left( \cfrac { 2 }{ 15 } \right)$

In figure, lines

$PQ$ and

$ST$ intersect at

$O$ . If

$\angle POR=90^o$ and

$x:y =3:2$ , then

$z$ is equal to

0%
$126^o$
0%
$144^o$
0%
$136^o$
0%
$154^o$

Explanation

We can see in the given figure,

$PQ$ is a straight line

$\therefore \angle POR +ROT +\angle TOQ =180^o$

$\Rightarrow 90^o +x+y=180^o$

$\Rightarrow x+y=90^o$

$\Rightarrow x+y=90^o$ ...(1)

Given that,

$\dfrac xy =\dfrac 32$

Let

$x=3K$ and

$y=2K$

From equation (1)

$\Rightarrow 3K+2K=90^o$

$\Rightarrow K=\dfrac{90^o}{5}$

$\Rightarrow K=18^o$

$\therefore y=2\times 18^o =36^o$

Now,

$SOT$ is a straight line

$\Rightarrow z+y=180^o$

$\Rightarrow z+36^o =180^o$

$\Rightarrow z=180^o-36^o$

$\Rightarrow z=144^o$

Hence, Option

$(B)$ is correct.

In figure, the value of

$x$ is

0%
$110^o$
0%
$46^o$
0%
$64^o$
0%
$150^o$

Explanation

Option (d) is correct.
As we knew, the angle made around a point is

$360$ degree.
Then,

$\therefore y+64^o +46^o +100^o -360^o$

$\Rightarrow y+210^o =360^o$

$\Rightarrow y=360^o -210^o$

$\Rightarrow y=150^o$

Measures of

$\angle ABC$ and

$\angle CBA$ in figure are the same.

0%
True
0%
False

Explanation

As ∠ABC and ∠CBA both represent the same angle formed at point B.

Hence, the measures of the ∠ABC and ∠CBA are the same.

$\textbf{Therefore, the given statement is true.}$

It is possible to have a triangle in which two of the angles are obtuse.

0%
True
0%
False

Explanation

False
By angle sum property we know,

$\angle A+ \angle B+ \angle C =180^{o}$
According to the question, two angles are obtuse,

$\therefore \angle B+ \angle C > 180^{o}$
Thus, Triangle is not possible

In figure, the reflex

$\angle AOB$ is equal to :

0%
$60^{\circ}$
0%
$120^{\circ}$
0%
$300^{\circ}$
0%
$360^{\circ}$
