If we have no pizza, and divided it between you and me, how much do we get? ZERO.

However, you want equivalent fractions to 0/2. To get an equivalent fraction, you multiply the numerator (the number on the top) and the denominator (the number on the bottom) by the same number.

So we can multiply the top and bottom by 2.

0 x 2 = 0

2 x 2 = 4

So an equivalent fraction would be 0/4.

Good luck.

Assuming that the angle at A is the right angle, Pythagoras' theorem says that the length of the hypotenuse (the side opposite the right angle) is the square root of the sum of the squares of the other two sides. In your case, AB and AC are 'the other two sides' and BC is the hypotenuse, so:

__ __ __ __

/ 2 2 /

length BC = V 10 + 20 = V 100 + 400

__ __

= V 500 = 22.36 cm

(To find the angle at C, you need trigonometry and is arc-tan(10/20)

and the angle at B is arc-tan(20/10) - 26.5 deg and 63.5 deg)

length BC = V 10 + 20 = V 100 + 400

tan(x/2)=sin(x)/(1+cos(x))

Setting x/2=45, means that x=90 (degrees)

But cos(90)=0 and sin(90)=1. Thus tan(45)=1/(1+0)=1.

But cos(90)=0 and sin(90)=1. Thus tan(45)=1/(1+0)=1.

I gues this problem has no solution because both

SinX and cosX should be between -1 and +1 so it's not possible that value of SinX - cosX should be 4

=>2x+3=0 ; taken x as common and 4-2=2 i.e. x(4-2) = 2x

=>2x=-3 ; +3's moved on the right-hand side, so it becomes -3

=>x=-3/2 ; 2 has been moved to the right-hand side and divided with -3 i.e 1/2 multiplied by -3 = -3/2

Good luck.

Thanks for using

Hii,here is list of basic real numbers properties applying them you can solve the problems easily.

Assuming a,b,c,d are real numbers:

**1)Commutative Property **

**a) Property of Addition**: a+b = b+a

**b)Property of Multiplication**: ab = ba

**2)Associative Property **

**a)Property of Addition**: (a+b) + c = a + (b + c)

**b)Property of Multiplication**: ( ab )c = a ( bc )

**3)Additive Identity**:

a+0 = a where 0 is the additive identity

**4)Additive Inverse**:

For real number a, there exists -a such that

a+(-a) = 0

**5)Multiplicative Identity**:

For real number a,

1 X a = a

where 1 is the multiplicative identity

**6)Multiplicative Inverse**:

For real number X where a≠0, there exists 1/asuch that

a X(1/a) = 1

**7)Zero Product Law**:

If ab = 0, then a=0 or b=0 or both a and b = 0.

**8)Distributive Properties**:

**a)Left distributive law**

a (b + c ) = ab + ac

** b)Right distributive law**

(a + b) c = ac+ bc

Assuming a,b,c,d are real numbers:

a+0 = a where 0 is the additive identity

For real number a, there exists -a such that

a+(-a) = 0

For real number a,

1 X a = a

where 1 is the multiplicative identity

For real number X where a≠0, there exists 1/asuch that

a X(1/a) = 1

If ab = 0, then a=0 or b=0 or both a and b = 0.

a (b + c ) = ab + ac

(a + b) c = ac+ bc

Assuming M is the intersection of MN with AB, and N is the intersection of MN and AC:

Angle ACP = angle BCP (by definition)

Angle NCP = angle BCP (intersection of line with parallel lines produces equal angles)

Triangle CPN is isoceles (two equal angles), and line NP = CN

Same argument for line MP = BM

Therefore NP + MP (i.e, MN) = CN + BM

Angle ACP = angle BCP (by definition)

Angle NCP = angle BCP (intersection of line with parallel lines produces equal angles)

Triangle CPN is isoceles (two equal angles), and line NP = CN

Same argument for line MP = BM

Therefore NP + MP (i.e, MN) = CN + BM

cscx=2 which can also be written as 1/sinx = 2/1

do the recipricol (flip it) and sinx = 1/2 which is pie/6 or 30 degrees.

tanx= sinx/cosx,

secx=1/cosx

1+sinx/cosx=3

1+sinx=3cosx---------->1

cosx=5-sinx------------->2

sub 2 in 1

1+sinx=3(5-sinx)

1+sinx=15-3sinx

1+4sinx=15

4sinx=14

sinx=14/4...

this is the solution..
