5x+x=90 degree
x=90\6
x=15
5x=15*5=75
75+15=90degree
Answer:
The 2 numbers are 512.8 and 487.2.
Step-by-step explanation:
Let the numbers be x and y, then:
x + y = 1000............(1)
x^2 - y^2 = 25600
(x + y)(x - y) = 25600
1000(x - y) = 25600
x - y = 25.6............(2)
Adding (1) + (2):
2x = 1025.6
x = 512.8
so y = 1000 - 512.8
y = 487.2.
Answer:
BC = 9 miles
Step-by-step explanation:
Here, we are given ΔABC ∼ ΔEDC, which means both triangles are similar and they tend to have the same dimensions and properties.
To find the length of BC, we are given the proportion:

Where x represents the length BC.
Solving further, let's cross multiply


Solving for x, we have:

Lets divide both sides by 8


Therefore the distance BC is 9 miles

<h3>How to match the tiles?</h3>
We start by evaluating each expression as follows:

Expand 972

Take the 5th root of 243

Rewrite as:
![972^\frac 15 = 3\sqrt[5]{4}](https://tex.z-dn.net/?f=972%5E%5Cfrac%2015%20%3D%203%5Csqrt%5B5%5D%7B4%7D)
Next, we have:

Expand 448

Take the 3rd root of 64

Rewrite as:
![448^\frac 13 = 4\sqrt[3]{7}](https://tex.z-dn.net/?f=448%5E%5Cfrac%2013%20%3D%204%5Csqrt%5B3%5D%7B7%7D)
Next, we have:

Expand 3528

Take the square root of 1764

Rewrite as:

Lastly, we have:

Expand 4050

Take the 4th root of 81

Rewrite as:
![4050^\frac 14 = 3\sqrt[4]{50}](https://tex.z-dn.net/?f=4050%5E%5Cfrac%2014%20%3D%203%5Csqrt%5B4%5D%7B50%7D)
