Well DCB is a right angle, and there is already half which is 53 degrees, subtract 90 by 53 and you will get your answer.
Answer:
147°
Step-by-step explanation:
The measure of arc CH is equal to the central angle it sees
the angles arc AH sees are BAC and CAH so the length of arc AH would be the sum of these two angles
90° + 57° = 147°
(2,5) equal 10
(-4,9) equal 5
But if you were taking away 10 - 5 equal 5
