You add the numbers up so 53
In A Circle:
If AB || CD ⇒ BC = AD = 16°
AB + BC + CD + AD = 360°
AB + CD + 2BC = 360°
48° + CD + (2*16°) = 360°
CD = 360° - 48° - 32°
CD = 280°
Claim: The difference between two rational numbers always is a rational number
Proof: You have a/b - c/d with a,b,c,d being integers and b,d not equal to 0.
Then:
a/b - c/d ----> ad/bd - bc/bd -----> (ad - bc)/bd
Since ad, bc, and bd are integers since integers are closed under the operation of multiplication and ad-bc is an integer since integers are closed under the operation of subtraction, then (ad-bc)/bd is a rational number since it is in the form of 1 integer divided by another and the denominator is not eqaul to 0 since b and d were not equal to 0. Thus a/b - c/d is a rational number.
Answer:
-48
