Question

if 2 sin (A+B) = √3 and tan B=1, find Sin2B​

Answer 1

Answer:

answer for the given problem is given

Answer 2

Step-by-step explanation:

2 sin (A+B) = √3

sin (A+B) = √3/2

sin (A+B) = sin60°

A + B = 60° ...................1

tanB = 1

tanB = tan45°

B = 45°

sin2B = sin2x45°

= sin90°

= 1
