Answer 1

Hey friend✋! here is your answer

____________________________

◆ To find - {2sin15° Cos75°}

✔️Formula => 2sinA cosB= sin(A+B)+sin(A-B)

✅By comparison - A=15° & B=75°

✔️2sin15° cos75°=

✅sin(15+75)+sin(15-75)

✔️Sin(90)+sin(-60)

✅1+(-√3/2). { sin90°= 1 & sin60°=√3/2}

✔️1-√3/2

✅Take LCm

✔️2-√3/2
So,

value of 2sin15° Cos75° is 2-√3/2
