Answer:

Step-by-step explanation:

Given the expression

9|4/3x-2| + 7 = 7

First note that the value in parenthesis can both be negative and positive;

For the positive value, we have;

9(4/3x-2) + 7 = 7

9(4/3x-2) + 7 - 7 = 7 - 7

9(4/3x-2) = 0

Open the bracket

9(4/3x) - 9(2) = 0

36/3 x - 18 = 0

12x = 18

x = 18/12

x = 3/2

For the negative value;

9(-(4/3x-2)) + 7 = 7

9(-4/3x+2) + 7 - 7 = 7 - 7

9(-4/3x+2) = 0

Open the bracket

9(-4/3x) + 9(2) = 0

-36/3 x + 18 = 0

-12x = -18

x = 18/12

x = 3/2

Hence the value of x is 3/2

Answer:

25.5

Step-by-step explanation:

first find the area od the rectangle than the triangle.

to find the area count the number of squares and use A=b*h

than do the same for the triangle using A=.5*b*h

15=3*5

10.5=.5*3*7

10.5+15=25.5

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 $\frac{\sqrt{2+\sqrt{3}}}{2}$ .
