Evaluate :- sin 60 cos 30 + sin 30 cos
60​

Answer 1

Answer:

it is in the form sin(A + B) = sinA cosB + cosA sinB

so it is equal to sin (60° + 30° ) = sin(90°) = 1

hope it helps u !!!!☺️☺️

Answer 2

Step-by-step explanation:

Evaluate :- sin 60 cos 30 + sin 30 cos  60​

Given  sin 60 cos 30 + sin 30 cos  60

• So by substituting the values for the above problem we have
•      Given sin 60 cos 30 + sin 30 cos 60
•          So √3 / 2 x √3 / 2 + 1/2 x 1/2  
•         So √3 x √3 / 2 x 2 + 1 / 4
•              = 3 / 4 + 1/4
•             = 3 + 1 / 4
•            = 4 / 4
•            = 1

Therefore sin 60 cos 30 + sin 30 cos 60 = 1
