Answer:
Is there any answer choices?
Step-by-step explanation:
Answer:
y = 4
x = 8
Step-by-step explanation:
here's the solution :-
we know, x = 2y
so,
=》x + y = 12
=》2y + y = 12
( because x = 2y )
=》3y = 12
=》y = 12 ÷ 3
=》y = 4
so, y = 4
now,
=》x = 2y
=》x = 2 × 4
( because, y = 4 )
=》x = 8
so, we get x = 8

Answer:</h2>
<em> The side of the triangle is either 38.63ft or 10.35ft</em>
<h2>
Step-by-step explanation:</h2>
This problem can be translated as an image as shown in the Figure below. We know that:
- The side of the square is 10 ft.
- One of the vertices of an equilateral triangle is on the vertex of a square.
- Two other vertices are on the not adjacent sides of the same square.
Let's call:
Since the given triangle is equilateral, each side measures the same length. So:
x: The side of the equilateral triangle (Triangle 1)
y: A side of another triangle called Triangle 2.
That length is the hypotenuse of other triangle called Triangle 2. Therefore, by Pythagorean theorem:
We have another triangle, called Triangle 3, and given that the side of the square is 10ft, then it is true that:
Therefore, for Triangle 3, we have that by Pythagorean theorem:
Matching equations (1) and (2):
Using quadratic formula:
Finding x from (1):
<em>Finally, the side of the triangle is either 38.63ft or 10.35ft</em>
