HELP ILL GIVE YOU BRAINLIEST

Alex Ar [27]

Answer:

1. Distributive Property

2. Addition Property of Equality

3. Multiplicative Property of Equality

Step-by-step explanation:

1. The 3 is multiplied by each number in the parenthesis

3*10=30

3*2=6

So 3*(10-2x)=30-6x

2. The 30 is subtracted from both sides

30-6x-30 = -6x

6-30 = -24

30-6x-30=6-30

So -6x=-24

3. The -6 is divided from both sides

-6x/-6 = x

-24/-6 = 4

-6x/-6 = -24/-6

So x=4

Find the exact value

Mnenie [13.5K]

By using properties for trigonometric functions and trigonometric expressions, we find that the exact value of the sine of the angle 5π/12 radians is $\frac{\sqrt{2+\sqrt{3}}}{2}$ .

<h3>How to find the exact value of a trigonometric expression</h3>

Trigonometric functions are trascendent functions, these are, that cannot be described algebraically. Herein we must utilize trigonometric formulae to calculate the exact value of a trigonometric function:

$\sin \frac{5\pi}{12} = \sqrt{\frac{1 - \cos \frac{5\pi}{6} }{2} }$

$\sin \frac{5\pi}{12} = \sqrt{\frac{1 + \cos \frac{\pi}{6} }{2} }$

$\sin \frac{5\pi}{12} = \sqrt{\frac{1 + \frac{\sqrt{3}}{2} }{2} }$

$\sin \frac{5\pi}{12} = \sqrt{\frac{2+\sqrt{3}}{4} }$

$\sin \frac{5\pi}{12} = \frac{\sqrt{2+\sqrt{3}}}{2}$

By using properties for trigonometric functions and trigonometric expressions, we find that the exact value of the sine of the angle 5π/12 radians is $\frac{\sqrt{2+\sqrt{3}}}{2}$ .

Solve this expression (1/6-3)+(3q-1.7)+(-1/3p+4)

QveST [7]

Step-by-step explanation:

Let's simplify step-by-step.

16−3+3q−1.7+−13p+4

=16+−3+3q+−1.7+−13p+4

Combine Like Terms:

=16+−3+3q+−1.7+−13p+4

=(−13p)+(3q)+(16+−3+−1.7+4)

=−13p+3q+−0.533333

Answer:

=−13p+3q−0.533333
