Answer:

$x=85^{\circ}$

Step-by-step explanation:

The sum of the interior angles of any polygon with five sides is equal to $(5-2)\cdot 180=3\cdot 180=540^{\circ}$ . Therefore, we can set up the following equation and solve for $x$ :

$115+95+115+130+x=540,\\455+x=540,\\x=\boxed{85^{\circ}}$

What is the midpoint of the segment shown below?

d1i1m1o1n [39]

Answer:

Step-by-step explanation:

Calculate the midpoint using the midpoint formula

[ 0.5(x₁ + x₂ ), 0.5(y₁ + y₂ ) ]

with (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (5, 5)

midpoint = [ 0.5(- 1 + 5), 0.5(5 + 5) ]

= [ 0.5(4), 0.5(10) ] = (2, 5 ) → A

<h3>What is a polygon?</h3>

A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides. Also, some examples of a polygon include the following:

Triangle
Quadrilateral
Pentagon
Hexagon
Heptagon
Octagon
Nonagon

<u>Note:</u> The number of sides (n) of a hexagon is 6.

In Geometry, the sum of the interior angles of both a regular and irregular polygon is given by this formula:

Sum of interior angles = 180 × (n - 2)

Sum of interior angles = 180 × (6 - 2)

Sum of interior angles = 180 × 4

Sum of interior angles = 720°.
