To find the value of the expression sin(21°)cos(24°) + sin(24°)cos(21°), we can use the trigonometric identities:
sin(A)cos(B) + sin(B)cos(A) = sin(A+B)
Therefore,
sin(21°)cos(24°) + sin(24°)cos(21°) = sin(21° + 24°)= sin(45°)= 1
So, sin(21°)cos(24°) + sin(24°)cos(21°) equals 1.

Therefore,
sin(21°)cos(24°) + sin(24°)cos(21°) = sin(21° + 24°)
= sin(45°)
= 1
So, sin(21°)cos(24°) + sin(24°)cos(21°) equals 1.
