Question

Find the value of sin 75° cos15°+cos 75°sin 15°


guys pls help me with this​

Answer 1

√3/2

Step-by-step explanation:

sin 75° cos 15°+cos 75°sin 15°

sin(75°+15°). {sin(A+B)= sinAcosB + cosAsinB}

sin(90°)

sin90°

$= \frac{ \sqrt{3} }{2}$

Answer 2

Answer:

1

explanation:

sin 75° cos15°+cos 75°sin 15°

$sina cosb + sinb cosa \: = \sin(a + b)$

sin 75° cos15°+cos 75°sin 15°=sin(75°+15°)

=sin90°
