Check the picture below.

notice the reflected gray line on the red one over the y=x line, the slope of either line across the y=x line is simply the other's upside-down.

\stackrel{\textit{slope of line "a"}}{a\implies \cfrac{a}{1}}\hspace{5em}\stackrel{\textit{slope of its reflection}}{\cfrac{1}{a}}

ad-work [718]

Answer:

40

Step-by-step explanation:

5 people in the room have  5*40 = 200 years altogether

a new person is X years old.

Now 6 people have (200 + x) years altogether.

Mean age of 6 people  is (200+x)/6. and it is also = 40.

(200+x)/6 = 40

200 + x = 240

x = 40

An equilateral triangle has a height of 10 feet. How long is one of its sides? (Note: In an equilateral triangle, all sides have
lidiya [134]

Answer:

side length is \frac{20\sqrt{3} }{3} feet

Step-by-step explanation:

An equilateral triangle has a height of 10 feet.  the height of the triangle is the perpendicular bisector to the base

so it forms a two right angle triangle

the triangle formed is a 30-60-90 degree triangle

the diagram is attached below

Let x be the side if the equilateral triangle

sin(theta)=opposite by hypotenuse

sin(60)=\frac{10}{x}

\frac{\sqrt{3}}{2} =\frac{10}{x}

cross multiply

\sqrt{3} x=20

x=\frac{20}{\sqrt{3} } =\frac{20\sqrt{3} }{3}
