Orange ribbon 2 meters long. The blue ribbon was 4/5 as long ad the orange. Linda cuts off a piece of blue ribbon. The length of

masha68 [24]

The initial length of the blue ribbon = 1.6 meters

Step-by-step explanation:

Here, according to the question:

The initial length of orange ribbon = 2 meters

Let us assume the initial length of blue ribbon = S meters

Now, the length of blue ribbon = (4/5) times the length of orange ribbon

$\implies S =( \frac{4}{5})$ x Length of Orange ribbon

$\implies S = (\frac{4}{5}) \times 2 = 1.6$

or S = 1.6 meters

Hence, the initial length of the blue ribbon is 1.6 meters.

Here we go !!

Since it's a regular pentagon, all it's sides are equal so let's solve for x

$\hookrightarrow \: 3(x - 1) = 5x - 6$

$\hookrightarrow \: 3x - 3 = 5x - 6$

$\hookrightarrow \: 3x - 5x = - 6 + 3$

$\hookrightarrow \: - 2x = - 3$

$\hookrightarrow \: x = \dfrac{ - 3}{ - 2}$

$\boxed{\boxed{x = \dfrac{3}{2} }}$

now let's find the measure of each side, i.e

$\hookrightarrow \: 5x - 6$

$\hookrightarrow \: (5 \times \dfrac{3}{2}) - 6$

$\hookrightarrow \: \dfrac{15}{2} - 6$

$\hookrightarrow \: 7.5 - 6$

$\mathrm{\hookrightarrow \: 1.5 \: units}$

perimeter = 5 × side length ( for a regular pentagon )

$\hookrightarrow \: 1.5 \times 5$

$\boxed{ \boxed{ \: \: \: \: \: \: \: \: 7.5 \: \: units \: \: \: \: \: \: \: }}$
