Vertical asymptote :- x = 4

y-intercepte:-
= 1/ 0- 4 + 5 = -5.25

Horiz. asymptote :- y = -5

x-intercept:- 1 / x- 4 - 5 = 0,
1 = 5x - 20
x = 19/5 = 4.2

The sum of the measures of angles in all quadrangles is 360 °. Therefore:

$(25x+1)+(25x-2)+(20x-1)+82=360\\\\70x+80=360\ \ \ |-80\\\\70x=280\ \ \ |:70\\\\x=4$

$m\angle D=(20x-1)^o\to m\angle D=(20\cdot4-1)^o=79^o\\\\Answer:\ B.\ 79^o$

Nikolay [14]

Answer:

5 units (you are right!)

Step-by-step explanation:

The triangles ABD and BCD are similar.

Therefore,

$\frac{x}{10}=\frac{10}{4x} \\4x^{2}=100\\x^{2}=25\\x=5$

I hope this helped!
