(1 - cos ß)(1 + cos ß) =1/cosec^2(ß)

iVinArrow [24]

Step-by-step explanation:

L.H.S=(1-cosB)(1+cosB)

=(1-cos^2B). {using (a+b) (a-b)=(a^2-b^2)in second step}

=sin^2B

=1/cosec^2B

Therefore,L.H.S=R.H.S proved

Q1. Look at the picture.

$C.\\y=-\dfrac{1}{3}x+3\\\\y=2x-4$

Q2. Look at the picture.

$A.\ 4-t$

Q3.

Put the value of x = 2 to the equation 3x + y = 5:

$3(2)+y=5$

$6+y=5$ subtract 6 from both sides

$y=-1\\\\F.\ -1$

Q4.

$\left\{\begin{array}{ccc}n=3m-11&(*)\\2m+3n=0&(**)\end{array}\right$

Substitute (*) to (**):

$2m+3(3m-11)=0$ use distributive property

$2m+(3)(3m)+(3)(-11)=0$

$2m+9m-33=0$ add 33 to both sides

$11m=33$ divide both sides by 11

$m=3$

Put the value of m to (*):

$n=3(3)-11\\\\n=9-11\\\\n=-2$

$C. (3,\ -2)$

Q5.

w - width

3w - length

24 in - the sum of length and width

The equation:

$w+3w=24$

$4w=24$ divide both sides by 4

$w=6\ in$

$3w=3(6)=18\ in$

$J.\ 18\ inches$
