Question

if sinA+sinB=2 what is the value of sin(A+B)


answer the question

Answer 1

This is in the form of (X × a)+(X × b)= 2

Then X(a + b)

Answer 2

Hello dear,

______

There is only one possibility for sin A + sin B to be equal to 2.

max. value of sin theta = 1
therefore, sin A = 1 and sin B = 1
therefore , A = B = 90°

sin (A+B) = sin (90°+90°)
= sin 180°
= 0
