Answer:
12
Step-by-step explanation:
For polygons that are similar to each other, the ratio of their corresponding sides are usually equal to each other, as they are proportional.
Therefore, given that ∆DAE is similar to ∆BAC, AD = 6, AB = 6+4 = 10, AE = x, AC = x + 8, therefore:
AD/AB = AE/AC
6/10 = x/(x+8)
Cross multiply
6*(x+8) = x*10
6x + 48 = 10x
Subtract 6x from both sides
48 = 10x - 6x
48 = 4x
Divide both sides by 4
48/4 = x
x = 12
Length of side AE = 12
5/10 = 1/2
8/18 = 4/9
1/2 > 4/9
They're not proportional.
Answer:
The distance is 4 units.
Step-by-step explanation:
Let the distance between the two points (x₁, y₁) and (x₂, y₂) is
<em>d = √(x₂ - x₁)² + (y₂ - y₁)²</em>
Here, the given points are (2,8) and (6,8), therefore,
x₁ = 2, x₂ = 6,
y₁ = 8, y₂ = 8
d = √(x₂ - x₁)² + (y₂ - y₁)²
d = √(6 - 2)² + (8 - 8)²
d = √(4)² + (0)²
d = √16
d = 4
Thus, The distance is 4 units.
