Question

If theta is equal to 45 then prove sin 2 theta is equal to 1

Answer 1

Step-by-step explanation:

There are still some rules and restrictions to women even though India is an independent country. The first and foremost issue that is facing by women is child marriages. It leads to the psychological, social, mental and physical issues for that young girl. Another problem is the acid attack. It happened many times in India. It is done with the intention of taking revenge on a girl by throwing acid.

Answer 2

Answer:

θ+2θ−45

∘

=90

∘

3θ=135

∘

θ=45

∘

=∠A

∠C=2θ−45

∘

=(2×45)−45

∘

=90

∘

−45

∘

=45

∘

Side opposite to equal angles are equal ∠A=∠C

So, BC=AB

So, tanθ=

AB

BC

=1

So 1 is correct.
