Mathematics
1 answer:
Darya [45]3 years ago
8 0

Answer:

0

Step-by-step explanation:

Sin 30° = ½

Cos 30° = √3/2

Sin 60° = √3/2

Cos 60° = ½

Therefore,

(½ + √3/2) - (√3/2 + ½)

\frac{1 +  \sqrt[]{3} }{2}  -  \frac{ \sqrt{3 + 1} }{ 2 }

\frac{1 +  \sqrt{3}  -  \sqrt{3}  -  1}{2}

\frac{0 - 0}{2}

Answer: 0

Which of the following represents “6 less
kykrilka [37]

Answer:

C) 3x - 6

Step-by-step explanation:

Let the unknown number be represented by placeholder x.

Then the product of 3 and the number is represented by 3*x or 3x.

This value diminished by 6 corresponds to 3x-6.

So the expression representing the required overall construct mathematically is given by 3x-6

Option a, 6x-3 represents the difference of 6 times x and 3.

Option b, 3-6x represents the difference of 3 and (6 times x).

Option d, 6-3x represents the difference of 6 and (3 times x).
