Answer:

Side length = 12 feet

Hypotenuse = 13 feet

Step-by-step explanation:

Area of a triangle is: A = (1/2)base * height

so,

30 = (1/2)5 * height

30 = 2.5 * height, divide by 2.5 from both sides

12 = height

Pythagorean theorem is a^2 + b^2 = c^2, where c is the hypotenuse

so,

5^2 + 12^2 = c^2

25 + 144 = c^2

169 = c^2, square root both sides

c = 13

balu736 [363]

the question in English

Juan has blue cubes with a 55 mm edge and red cubes with a 45 mm edge. He stacks them in two columns, one of each color; he wants the two columns to be the same height. How many cubes does he need, as a minimum, of each color?

Let

x---------> the number of blue cubes

y--------> the number of red cubes

we know that

Juan wants that the two columns to be the same height

$55x=45y$

solve for y

$y=\frac{55}{45}x$

I proceed to calculate a table, assuming values of x to calculate the value of y. When the values of x and y are whole numbers, I will have found the solution.

the table in the attached figure

therefore

<u>the answer is</u>

9 blue cubes

11 red cubes
