Answer:

-4

Step-by-step explanation:

One-quarter of the sum of 2 consecutive odd numbers is 14. Find the numbers.

aalyn [17]

Answer:

27 and 29

Step-by-step explanation:

let A and B the expected numbers

assuming B = A + 2, the problem can be written as follows

¼(A + A + 2) = 14

4*¼(A + A + 2) = 4*14

(A + A + 2) = 56

2A + 2 = 56

A + 1 = 28

A = 27

B = 27 + 2 = 29

Given: Circle O,

Lunna [17]

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°
