7. a =4, b=

2 \sqrt{2}

Step-by-step explanation:

6.

\tan(30)  =  \frac{b}{11 \sqrt{3} }  \\ or \:  \: ( \frac{1}{ \sqrt{3} } ) =  \frac{b}{11 \sqrt{3} }  \\ or \:  \:  \: b = 11 \\ and \:  \sin(30)  =  \frac{11}{a}  \\ or \:  \ \:  \frac{1}{2}  =  \frac{11}{a}  \\  \:  \:  \:  \: a = 22

What is the area of a regular hexagon with a distance from its center to a vertex of 1 cm? (Hint: A regular hexagon can be divid
devlian [24]
<h3>Answer:</h3><h3>Exact area = \frac{3}{2}\sqrt{3} square cm</h3><h3>Approximate area = 2.598 square cm</h3>

=================================================

Work Shown:

s = side length of equilateral triangle = 1 cm

A = area of equilateral triangle with side length 's'

A = \frac{\sqrt{3}}{4}*s^2

A = \frac{\sqrt{3}}{4}*1^2

A = \frac{\sqrt{3}}{4}

This is just one of the 6 equilateral triangles (see diagram below)

Multiply by 6 to get the area of all 6 equilateral triangles, or the entire hexagonal area

6*A = 6*\frac{\sqrt{3}}{4}

6A = \frac{3\sqrt{3}}{2}

6A \approx 2.598

2x - 4 - 6(x + 1) = 5x + 6 a) 8 b) -8/9 c) 4 d) -16/9
andriy [413]
<h2>d) X= - 16/9</h2>

Step-by-step explanation:

2x - 4 - 6(x + 1) = 5x + 6

2x - 4 - 6x - 6 = 5x + 6

2x - 6x - 5x = 4 + 6 + 6

-9x =16

x= -16/9
