The diagonals of a kite meet at 90°. It is filled from A option.
It is a line segment which joins two vertices of a shape when those vertices are not on the same edge.
The shape of a kite is rhombus whose all sides are equal to each other. Because all the sides are equal to each other, the triangles formed by the diagonals of the rhombus are congruent and the angle made on a line is equal to 180 degrees. By dividing the line into two equal parts by bisecting we can find all angles at which the diagonals are bisecting equal to 90 degrees.
Hence the diagonals of a kite meets at a right angle.

Answer: y = -x + 5 and y = -x - 7 (see attached graph)
Step-by-step explanation:
y =
= 9(x + 1)⁻¹
Use the product rule to find the derivative
a = 9 a' = 0
b = (x + 1)⁻¹ b' = -(x + 1)⁻²
ab' + a'b
= 9[-(x + 1)⁻²] + 0[(x + 1)⁻¹ ]
=
Set the derivative equal to the desired slope of -1 to solve for x
-1 =
-(x + 1)² = -9
(x + 1)² = 9
√(x + 1)² = √9
x + 1 = +/- 3
x + 1 = 3 x + 1 = -3
x = 2 x = -4
Plug those values into the original equation to solve for y:
y =
=
= 3
(2, 3)
y =
=
= -3
(-4, -3)
Next, plug in the given slope (-1) and the coordinates above into the Point-Slope formula y - y₁ = m(x - x₁) to find the equations:
m = -1, (x₁ y₁) = (2, 3) m = -1, (x₁ y₁) = (-4, -3)
y - 3 = -1(x - 2) y + 3 = -1(x + 4)
y - 3 = -x + 2 y + 3 = -x - 4
y = -x + 5 y = -x - 7

First tangent line:
Second tangent line:
Notice: slope of -1 means that both are equal to -1, so
