Answer:
62
31
Step-by-step explanation:
AOD is right angled triangle, AOC = 90 - 28 = 62
ABC = AOC/2 , it is half the central angle
6 5/6 - 5 1/12
6 5/6 x 2
6 10/12 - 5 1/12
6-5=1
10-1= 9
( You don't subtract the 12s in subtraction)
1 9/12
Simplified
1 9/12 both divided by 3
1 3/4
Final answer 1 9/12

Answer:
33 degrees
Step-by-step explanation:
Because of the little square in the corner of the triangle, you know that that angle is 90 degrees. Since the second angle is 57 degrees and all of the interior angles of a triangle add up to 180 degrees, the final angle is 180-90-57=33 degrees. Hope this helps!
