Find x and the perimeter of the triangle. <br><br> x= <br> perimeter=
agasfer [191]

Answer:

x = 10  Perimeter: 129

Step-by-step explanation:

FINDING X:

4x+7 = 5x -3

7 = x -3

10 = x

x = 10

PERIMETER:

4x + 7 + 5x - 3 + 4x - 5

Combine the "x" values

13x + 7- 3 - 5

Combine the numbers

13x - 1

13(10) -1

130 - 1

Andrea has 3 tiles. One is a regular octagon, one is a regular pentagon and one is a regular hexagon. Andrea thinks the 3 tiles
HACTEHA [7]

From calculations, we can say that the given tiles will not fit together perfectly.

<h3>How to find the sum of interior angles of a Polygon?</h3>

If the tiles join perfectly at a point, sum of all angles around the joining point should be 360°.

Expression for the measure of the interior angle of a polygon,

Interior angle of a polygon = [(n - 2) * 180]/n

Interior angle of a pentagon = [(5 - 2) * 180]/5 = 108°

Interior angle of a hexagon = [(6 - 2) * 180]/6 = 120°

Interior angle of an octagon = [(8 - 2) * 180]/8 = 135°

To prove that the given tiles fit together perfectly → Sum of all the angles around the common point should be 360°

Sum of all interior angles = 108° + 120° + 135° = 363°

Therefore, given tiles will not fit together perfectly.
