Answer:
arc AB = 49°
arc ABC = 253°
arc BAC = 156°
arc ACB = 311°
Step-by-step explanation:
arc AB sees the center angle and it is equal to the center angle it sees
arc ABC is equal to 360 - 107 = 253° because it is also sees center angle
arc BAC is equal to 107 + 49 = 156°
arc ACB is equal to 360 - 49 = 311°

Answer:
<h2>
0.235 = 47/100</h2><h2>
0.5777 = 5777/10000</h2>
Step-by-step explanation:
Given the decimal numbers 0.235 and 0.5777, to show in the form p/q means we are to express the decimals in fraction in its lowest form. This is as shown below;
0.235 = 235/1000
= 5*47/5*200
= 47/200
0.235 = 47/100 where p = 47 and q = 200
For 0.5777
0.5777 = 5777/10000
This fraction can not be expressed further into its lowest term therefore p = 5777 and q = 10000
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>
