Question

please tell me the answer.

my friend wants this answer he is in class 10.​

Answer 1

Answer:

We know that, π=180°

L.H.S. ----So, we get, (sin 180°/3×tan180°/6) +=(sin180°/2×cos180°/3)

=(sin60°×tan30) +(sin90°×cos60°)

=(√3/2×1/√3) +(1×1/2)

=1/2+1/2

=1

R.H.S.-----2sin^2180°/4

=2sin^245°

=2(1/√2)^2

=2×1/2

=1

Hence, Proved

Answer 2

Answer:

Answer:-

sin60.tan30+sin 90 cos 60=2sin²45

LHS:-

sin60. sin30/√(1-sin²30)+ sin90.cos(90-30)

(sin 60.sin 30)

____________+. sin 90.sin30

√(3/4)

2 sin60.sin30

___________+ sin 90.sin30

√3

sin30+sin90.sin30

sin 30(1+sin90)

1

_(1+1). =. 2/2. =. 1

2

RHS:-

2sin²45= 1

LHS=RHS

hence proved

hope it's helped you siso.........

it is my opinion only.......
