The 4,x, y,14and a half in arithmetic progression find x and y

maybe

Step-by-step explanation:

x+y=14 (i)

x−y=4 (ii)

From (ii) y=x−4 ...(iii)

Substituting y from (iii) in (i), we get

x+x−4=14

⇒2x=18

⇒x=9

Substituting x=9 in (iii), we get

y=9−4=5,

i.e, y=5

x=9,y=5

drop out of school or go to quizlet, quizlet is better

step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
