Question

x and y are points on sides ab and ac respectively of triangle abc. for which​

Answer 1

Answer:

B

Step-by-step explanation:

If XY || BC, then the corresponding angles are equal

angle AXY = angle ABC ,,

angle AYZ = angle ACB

and also,, angle A = angle A

∆ ABC is similar to ∆ AXY (AAA similarity criterion)

• AB/AX = AC/AY
• (AX + BX) / AX = (AY + YC ) / AY
• 1 + BX/AX = 1 + YC/AY
• BX/AX = YC/ AY
• OPTION B- 3.9/1.3 = 8.4/ 2.8 = 3
