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

$\bf{Hello!}$

The answer is 140°

Because we can use exterior angle property here

Exterior angle property : It states that exterior angle is the sum of two opposite interior angles

y = 120 + 20 = 140°

Question of the day.

matrenka [14]

$\lambda = _0^{200}\sum (i)^f = 1+50(i-1-i+1) = 1 + 0i$
From this we know that $\lambda$ lies on the x-axis.
If z = 0, then k = $\lambda$ and point lies on curve L.

I believe the answer is C. It definitely not A or B.
