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
Get them to have a common denominator so you can add them
(1/3)×2= 2/6 and (1/2)×3= 3/6
Add them together
(2/6)+ (3/6)= 5/6
So 5/6 of the class planted either marigolds or tulips and 1/6 of the class planted neither
Answer:
Plants use capillary action to bring water up the roots and stems to the rest of the plant. Therefore, if the plant could not do this the plant would die.

What is the question ????
i do not understand what the question is
Traiangle ABE = triangle CBD this is wrote right
bc. to angle A corespond angle C
and to angle B corespond angle B
and to angle E corespond angle D
so and than you check this posted image these coresponding angles are congruent angles what mean that these two triangles are congruent
