Answer:

It is a rational number.

Step-by-step explanation:

A number is only irrational if it has a decimal that never ends and doesn't have a pattern. So a number like Pi (3.141592653589...) is irrational while a number like 1/3 (0.33333333...) is rational.

Hi :)

Below is the difference between rational & irrational numbers

<h2>______________</h2><h3>RATIONAL</h3>

A number that can be expressed in $\sf{\dfrac{p}{q}}$ form, where $\large\boldsymbol{q\ne0}$

Evidently,

An irrational number is a number that cannot be expressed in $\sf{\dfrac{p}{q}}$ form

Let's test the given number, $\boldsymbol{3\dfrac{1}{4}}$

Well isn't it already in $\sf{\dfrac{p}{q}}$ form? It is.

Thus

$\longrightarrow\darkblue\boldsymbol{3\dfrac{1}{4}\:is\:rational}$

From a point A that is 8.20 m above level ground, the angle of elevation of the top of a building s 31 deg 20 min and the angle

Mariulka [41]

Answer:

30.11 meters ( approx )

Step-by-step explanation:

Let x be the distance of a point P ( lies on the building ) from the top of the building such that AP is perpendicular to the building and y be the distance of the building from point A, ( shown in the below diagram )

Given,

Point A is 8.20 m above level ground,

So, the height of the building = ( x + 8.20 ) meters,

Now, 1 degree = 60 minutes,

⇒ $1\text{ minute } =\frac{1}{60}\text{ degree }$
