What are the side lengths of the equilateral triangle?

Alchen [17]

$5x + (6x - 5) + (3x + 10) = 360$

$5x + 6x - 5 + 3x + 10 = 360$

$11x - 5 + 3x + 10 = 360$

$14x + 5 = 360$

$14x = 360 - 5$

$14x = 355$

$x = 25.36$

$x = 25.36$

$5x = 5 \times 25.36 = 126.8$

$6x - 5 = 6 \times 25.36 - 5 = 147.16$

$3x + 10 = 3 \times 25.36 + 10 = 86.08$

280 is divided between Krutika, Natasha & Richard so that Krutika gets twice as much as Natasha, and Natasha gets three time

Tasya [4]

Answer:

Natasha gets 84

Step-by-step explanation:

Here, we want to know how much Natasha gets

Krutika gets 2 times as much as Natasha

If Natasha gets x, Krutika gets 2x

If Natasha gets x, Richard will get x/3 ( 3 times of this is what Natasha gets)

Now let us have a ratio;

K : N : R

2x : x : x/3

Multiply through by 3

6x : 3x : x

To get the amount Natasha gets, we add up all ratio; (6x + 3x + x ) = 10x

Natasha gets 3x of the total ratio

That will be;

3x /10x * 280

= 3/10 * 280

= 84
