Sorry sir... but the screen is blurry. ; u ;
Holy @$#% THAT LOOKS HARD! Sorry, I can't help I don't know that math yet.
5 and 10 because 5x10 = 50 and 5+10 = 15
Answer:
Explanation:
Assuming that is a diameter, and that the angle of an arc subtending the central angle is congruent, .
And according to the arc addition postulate, .
Using the substitution property:
.
Given that .
Using the substitution property and that the measures apply to the arc addition postulate, .
.
.
Since and are subtending the center of the circle, they form vertical angles and are therefore congruent.
According to the definition of a vertical angle, .
Using the arc addition postulate again,
Using substitution, as well as how we are given that the central angle subtended by = 83°, we can find that:
