Question

2sin30°+Cos30°​

Answer 1

Ответ:

2sin30°+cos30°√3=2*½+√3/2*√3=1+3/2=(2+3)/2=5/2=2½=2,5.

Answer 2

To calculate the value of 2sin(30°) + cos(30°), you can use the values of sine and cosine for 30 degrees, which are:

sin(30°) = 0.5 cos(30°) = √3/2

Now, substitute these values into the expression:

2sin(30°) + cos(30°) = 2 * 0.5 + √3/2

Now, calculate each part of the expression:

2 * 0.5 = 1 √3/2 = √3/2

So, the final result is:

1 + √3/2

You can leave it in this form, or you can convert it to a decimal if needed:

1 + √3/2 ≈ 1 + 1.732/2 ≈ 1 + 0.866 ≈ 1.866

So, 2sin(30°) + cos(30°) is approximately 1.866.
