Answer:
Required value of x is 0.5 and y is 1.5.
Step-by-step explanation:
In the provided figure, ∠EAB = ∠FAC and EF || BC( given ).
Since EF is parallel to BC,
= > ∠EAB = ∠ABC = ∠FAC = ∠ACB ( alternate ∠s ) ...( i )
Also, given that the AD is perpendicular to BC,
= > ∠ADB = 90 = ∠ADC ( right angles ). ...( ii )
Thus, in ΔABD and ΔACD,
= > ∠ABC = ∠ACB { from ( i ) }
= > ∠ADB = ∠ADC { from ( ii ) }
= > AD = AD { common }
Hence, ΔABD ≅ ΔACD. And by c.p.c.t, AB = AC and BD = DC.
Therefore,
= > 2x - 3 = 3 - 2y Also x + 1 = y ...( iii )
= > 2x - 3 = 3 - 2( x + 1 )
= > 2x - 3 = 3 - 2x - 2
= > 2x - 3 = 1 - 2x
= > 2x + 2x = 1 + 3
= > 4x = 4
= > x = 1
Substituting the value of x in ( iii ),
= > x + 1 = y
= > ( 1 ) + 1 = y
= > 2 = y
Hence the required value of x is 1 and y is 2.
