Answer:
x=18
Step-by-step explanation:
all the interior angles in a pentagon = 540. use to interior angle theorem. then just add all the angles up and make them = to 540 like this: 540=95+90+(7x-4)+(3x+23)+(9x-6). then solve using algebra
Answer:
+12.5%
Step-by-step explanation:
This is rather simple. Subtract 72 from 81, then put the difference over 72. Then, multiply that by 100.
(81 - 72)/72 * 100
<em>Subtract 72 from 81 to get 9</em>
9/72 * 100
<em>Multiply 9 by 100 to get 900</em>
900/72
<em>Simplify the above fraction by cancelling out 9.</em>
100/8
<em>Divide 100 by 8 to get 12.5%</em>
The percent of change is +12.5%
Answer:
