90 + x + 107 + 144 + 138 = 540

479 + x = 540

x = 540 - 479

x = 61

Answer:

x=61°

Step-by-step explanation:

There are 5 sides in a polygon.

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

[tex](5-2) \cdot 180=540[/tex]

The sum of interior angles in a polygon is 540 degree

Now add all the interior angles and set it to 540

Right angle is 90 degree

[tex]90+x+138+144+107= 540[/tex]

[tex]479+x= 540[/tex]

Subtract 479 from both sides

[tex]x=61[/tex]
