Question

5(sin100° cos27° + sin 27°cos100°)​

Answer 1

Answer:

3.9931775502 is the answer of this question

Answer 2

Answer:

5(sin 100°×cos 27°+cos 100°×sin 27°)

as we know sinA×cosB+sinB×cosA= sin (A+B)

so 5(sin (100+27))

     =5(sin (127)°)

     =5(sin(90°+37°)

as sin 90+Ф=cosФ

so=5cos 37°

cos 37°=4/5

so =5×4/5

= 4
