Answer 1

Answer:

AC = 7cm

YC = 14 cm

AC = 21 cm

AB/AX = AC/ AY

Step-by-step explanation:

Given that

BX = AY

Therefore BX = AY = 7 cm

By Basic Proportionality Theorem,

AX/XB = AY/YC

3.5/7 = 7/YC

YC = 49/3.5 = 14 cm

AX+1/XB = AY +1 / YC ( Adding 1 on both sides)

AB / AX = AC / YC (Taking LCM)

HENCE PROVED

Answer 2

Step-by-step explanation:

AX=3.5 cm

AX=3.5 cmBX=7 cm

AX=3.5 cmBX=7 cmAY=BX=7 cm

BC is parallel to XY

BC is parallel to XYTherefore by Basic Proportionality Theorem

AX÷BX =AY÷YC

3.5÷7 = 7÷YC

(3.5×7)÷7 = YC

Therefore,

YC = 3.5 cm

a) AX = 3.5, BX= 7, AY=7, YC=3.5

b) AB÷XB = 【AC】÷AY
