Answer:
<em>x = 59</em>
Step-by-step explanation:
<u>Equations</u>
The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
The image shows a four-sided polygon and its four angles measures, thus we sum them all and equate the sum to 360:
x + x + 2x + 3 + 2x + 3 = 360
Simplifying:
6x + 6 = 360
Subtracting 6:
6x = 354
Dividing by 6:
x = 354/6
x = 59
Answer:
Distribute the -6 and combine like terms which are the x's
Also combine the numbers
Step-by-step explanation:
21.5 means 21 and 5 tenths and is read that way.
21.5 = 21 5/10 =(21*10 + 5) /10 = 215/10 = 43/2 in simplest terms
