Question

what is the value of sin17° cos 13°+cos 17° sin 13°​

Answer 1

Hey user ,

here is ur solution .....

Answer 2

value of sin17° cos 13°+cos 17° sin 13°​  = 1/2

Step-by-step explanation:

sin17° cos 13°+cos 17° sin 13°​

we will use Concept

Sin(A + B) = SinACosB + CosA SinB

now comparing

sin17° cos 13°+cos 17° sin 13°​   with SinACosB + CosA SinB

=> A  = 17°   & B =  13°​

Hence

sin17° cos 13°+cos 17° sin 13°​    = Sin( 17° +  13°​)

= Sin 30°

Value of  Sin 30° = 1/2

=> sin17° cos 13°+cos 17° sin 13°​    =  1/2
