Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 20) and (x₂, y₂ ) = (4, 10) ← 2 points on the line
m = =
=
Note the line crosses the vertical axis at (0, - 20) ⇒ c = - 20, thus
f(x) = x - 20 → A

Hey there! :D
We will use the properties of similar triangles to figure this out.
We will use two triangles inside the kite, with sides with the value of "x".
Smaller triangle:
Smaller side= 11
Bottom side= x
Bigger triangle:
Smaller side= x
Bottom side= 25
Cross multiply.
25*11= 275
x*x=
Find the square root.
√275= 16.583....
Or 5√11.
I hope this helps!
