Answer:

$\large\boxed{1\dfrac{16}{19}}$

Step-by-step explanation:

$5\div2\dfrac{5}{7}\qquad\text{convert the mixed number to improper fraction}\\\\2\dfrac{5}{7}=\dfrac{2\cdot7+5}{7}=\dfrac{19}{7}\\\\=5\div\dfrac{19}{7}=5\cdot\dfrac{7}{19}=\dfrac{(5)(7)}{19}=\dfrac{35}{19}=1\dfrac{16}{19}$

Find the unknown side lengths

GrogVix [38]

Step-by-step explanation:

h = x

p = 10

b = 24

using pythagorean theorem

h² = p² + b²

h² = 10² + 24²

h² = 676

h = 26

thus , x = 26

A polygon is regular if each of its sides has the same length. Find the perimeter of the regular polygon.

OleMash [197]

Answer: 6units

Step-by-step explanation:

Since it is a regular polygon, and it has 3 equal sides it means the polygon is a quadrilateral.

From the diagram,

5 - 2x = -4x + 9 ( side of quadrilateral )

Solving for x in the equation

-2x + 4x = 9 - 5 ( collection of like terms in simple linear equation )

2x = 4

Divide through by the coefficient of x which is 2

x = 2.

Therefore, the perimeter of the polygon which equals to the total length of the polygon is

Perimeter = 2 + 2 + 2

= 6units
