Answer: x = 10.5

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

Work Shown:

BC*BD = AB*AB
2*(2+x) = 5*5
4+2x = 25
2x = 25-4
2x = 21
x = 21/2
x = 10.5

Find the length of diagonal XU in the hexagon below. Round your solution to 2 decimal points
SpyIntel [72]

Answer:

The length of diagonal XU is 6.40 units

Step-by-step explanation:

* Lets explain how to find the distance between two points

- The rule of the distance between two points (x_{1},y_{1})

 and (x_{2},y_{2}) is:

 d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

* Lets solve the problem

-From the attached figure:

- The coordinates of the vertex X are (2 , 2)

- The coordinates of the vertex U are (-2 , 7)

∴ The point (x_{1},y_{1}) = (2 , 2)

∴ The point (x_{2},y_{2}) = (-2 , 7)

∴ x_{1}=2,x_{2}=-2

∴  y_{1}=2,y_{2}=7

∵ d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}

∴ d=\sqrt{(-2-2)^{2}+(7-2)^{2}}=\sqrt{(-4)^{2}+(5)^{2}}=\sqrt{16+25}=\sqrt{41}

∵ \sqrt{41}=6.403124

∴ d = 6.40

* The length of diagonal XU is 6.40 units

find the slope of the line on the graph write your answer as a fraction or a whole number not a mixed number or decimal
Alexandra [31]
The slope is (4,3). You look at the y intercept (where the y axis is crossed by the line) and simply count rise over run until you reach the next point. The next point from the y intercept (-2,0) is (2,3).

-2+4=2
0+3=3

And there you go. In fraction form it’s 4/3.
Hope this helped!

Find tan if sin=1/4 and falls in Quadrant 1
borishaifa [10]
Ok, sin = prep / hyp    

so,  perpendicular  = 1  , and hypo = 4  
so, base = sq. root ( 16-1 ) = root 15

and tan = prep / base  = 1 / root (15)
