2.	LACRUISE14.11. Draw a line parallel to a line p throughto a line p through a point R outside it.
Answer» Step-by-step explanation: In physics, a FORCE is any interaction that, when unopposed, will change the MOTION of an object. A force can CAUSE an object with MASS to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a PULL. A force has both magnitude and direction, making it a vector quantity

12.

If sin A = 3/4, Calculate cos A

Answer»

Step-by-step EXPLANATION:

Given:-

Sin A= 3/4

To find:-

CALCULATE cos A

Solution:-

Given Sin A=3/4

on squaring both sides then

=>(Sin A)^2 = (3/4)^2

=>Sin^2 A = 9/16

=>1- Sin^2 A = 1-(9/16)

=>Cos^2 A=(16-9)/16

=>Cos^2 A=7/16

=>Cos A=√(7/16)

Cos A=√7/4

(or)

Sin A= 3/4

=>Opposite side to angle A / Hypotenuse =3/4

Let the opposite side = 3x

Hypotenuse =4x

By Pythagoras theorem

Opposite side ^2+ Adjacent side^2 =Hypotenuse^2

=>(3x)^2+Adajacent side^2=(4x)^2

=>9x^2+adajacent side^2=16x²

=>Adajacent side^2=16x^2-9x^2

=>adjacent side^2=7x^2

=>Adjacent side=√(7x^2)

Adjacent side =√7 x

Now,

Cos A= Adjacent side / Hypotenuse

=>Cos A= √7 x/4x

Cos A=√7/4

Answer:-

The value of Cos A=√7/4

Used FORMULAE:-

Sin A= Opposite side to angle A / Hypotenuse
Cos A=Adjacent side to angle A / Hypotenuse
Sin^2 A+ Cos^2 A=1
Sin^2A= 1-Cos^2 A

15.	Find the centre and radius of the circle x2 + y2 - 2x - 2y = 0
Answer» Given Equation $x^2+y^2-2x-2y$ $=(x^2-2x+1)+(y^2-2y+1)-2$ $=(x-1)^2+(y-1)^2-2$ $\therefore (x-1)^2+(y-1)^2=2$ Application of Distance Formula $\sqrt{(x-1)^2+(y-1)^2} =\sqrt{2}$ → The distance from $(x,y)$ and $(1,1)$ is $\sqrt{2}$ . [Distance Formula] Thus, this equation FORMS a CIRCLE with center $(1,1)$ and RADIUS of $\sqrt{2}$ .

15.

Find the centre and radius of the circle x2 + y2 - 2x - 2y = 0

Answer»

Given Equation

$x^2+y^2-2x-2y$

$=(x^2-2x+1)+(y^2-2y+1)-2$

$=(x-1)^2+(y-1)^2-2$

$\therefore (x-1)^2+(y-1)^2=2$

Application of Distance Formula

$\sqrt{(x-1)^2+(y-1)^2} =\sqrt{2}$

→ The distance from $(x,y)$ and $(1,1)$ is $\sqrt{2}$ . [Distance Formula]

Thus, this equation FORMS a CIRCLE with center $(1,1)$ and RADIUS of $\sqrt{2}$ .
