Question

If sin^2 A + sin^2 B = 2 , then A + B =​

Answer 1

Answer:

0°

Step-by-step explanation:

\begin{gathered}\sin 2B = 2\sin B \\\\\sin 2\theta = 2 \sin\theta\cos\theta\\\\2 \sin B \cos B =2 \sin B\end{gathered}

sin2B=2sinB

sin2θ=2sinθcosθ

2sinBcosB=2sinB

\cos B = \frac{2\sin B }{2\sin B}cosB=

2sinB

2sinB

\begin{gathered}\cos B =1\\\\\cos B = 0\\\\\angle B = 0^\circ\end{gathered}

cosB=1

cosB=0

∠B=0

∘

hence , The value of B is 0°
