Question

Sin (A+B)=1 and cos A=root 3/2 then sin B equals to ?​

Answer 1

see the figure in attachment

hope it's helpful...

Answer 2

Step-by-step explanation:

Sin(A+B)=1

then,A+B=90. ........ first equation(1)

(Since sin90° =1)

Now,

CosA=√3/2

then,A=30°...... second equation(2)

(Since,Cos30°=√3/2)

from 1 and 2,we get

B=60

therefore,SinB=Sin60°=√3/2
