Question

What is the value of tan 0, if 0 and 20 - 45° are acute angles such that sin 0 = cos (20 - 45°)?​

Answer 1

Answer:

Correct option is

A

1

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
