the answer is 153.86 ft squared
= the formula for the area of a circle is A=πr2
= area = pi x radius squared
= the radius is 7 feet, square that to get 49
= multiply 49 by pi to get the area: 153.86 square feet
153.86 ft squared
x = 7
isolate x by dividing both sides by - 2
x = 
= 7
add all known angles:
90 + 107 + 144 + 138 = 479
the interior angles of a 5 sided polygon need to equal 540
540 - 479 = 61
x = 61 degrees
Answer: 44°
Step-by-step explanation:
Measures of the angles of a triangle
= 180°
Therefore, 180 - 105 + 31 = 44°
The range is correct because its largest to smallest
