Let the measure of an angle be 'x'
Then the reflex angle will be measured by the formula (360-x)
x +(360-x) = 360
Answer:
Step-by-step explanation:
arranging in ascending order
4,5,5,7,8,8,8,10,10
n=9
median=(9+1)/2=5th term=8
Answer:
1/3
Step-by-step explanation:
The sum of interior and exterior angle is 180, thus<span>Interior angle =180−72=108 degrees </span>Let n be the number of sides of the polygon<span><span>(n−2)×180 / n = interior angle =108</span></span><span>72n = 360</span><span> n = 5 sides, hence this is a pentagon.
Sum of the interior angles = 108*5 = 540 degrees.</span>
