Question

It's urgent

2 sin 30 degree + tan square 45 degree - cos square 150 degree

Answer 1

Answer:

We know that ,

Sin 30° = 1/√2

Tan 45° = 1

Cos 150° = -√3/2

Now putting the values in the given relation, we get

2(1/√2) + 1 - (-√3/2)

⇒√2 + 1 + √3/2

⇒2√2+2+√3/2            -----------------(after taking LCM)

So this is your answer

hope this helps!!!!!!!

Answer 2

Answer:

Step-by-step explanation:

Sin 30=1/2

Tan 45=1

Cos 150=cos(180-30)=cos 30=root 3/2

Therefore according to the conditions...

2×1/2+1-root3/2whole square

=2-3/4

8-3/4

=5/4
