Answer:

\cos x=\dfrac{8}{f}

Step-by-step explanation:

Given that,

\tan x=\dfrac{e}{8}\\\\\sin x=\dfrac{e}{f}

We need to find the value of cos x.

We know that,

\tan\theta=\dfrac{\sin\theta}{\cos\theta}

Using the above relation,

\dfrac{e}{8}=\dfrac{\dfrac{e}{f}}{\cos x}\\\\\cos x=\dfrac{\dfrac{e}{f}}{\dfrac{e}{8}}\\\\=\dfrac{e}{f}\times \dfrac{8}{e}\\\\=\dfrac{8}{f}

So, the value of cos x is equal to \dfrac{8}{f}.

OX and OY are two straight lines which intersect at an acute angle of 60°. OX = 4.5cm and OY = 5cm . The point M is on OX such t
Neko [114]

Therefore the point P is at 3.46 cm from O and it lies on the angle bisector of ∠XOY

<h3>What is an Angle Bisector ?</h3>

The ray that bisects the angle into half is called Angle Bisector.

It is given that ∠XOY = 60 degree

the length of OX = 4.5 cm

OY =5 cm

The point M is on OX such that

OM = 2 MX

so The M is at 3 cm from O

The point P lies in the acute angle such that the distance between point P and OX and OY is always same and at 3 cm from M

According to the angle bisector theorem converse states that if a point is in the interior of an angle and is at equal distance from the sides  then it lies on the bisector of that angle.

As it can be seen from the image that a point equidistant from the rays , at 3 cm from M will be at

By Pythagoras Theorem

3² +3² = OP²

OP = 2\sqrt{3} = 3.46 cm from O

The circumference of a circle is 121 3.14 cm, what is the area in term of pie
Tju [1.3M]
The circumference of a circle is determined by the formula 2πr.
I'd say divide the circumference by two and youll be left with 60.5=πr .
then divide 60.5 by 3.14 to get r
which is approximately 19.26
now use the circle formula for area
A=πr²
A in terms of pi is
A = π*(19.26)²
