Question 37 (ii) (ii) If DP = 50 cm and PE = 70 cm then find ππ/πΈπΉ.Since Ξ DPQ ~ Ξ DEF And, we know that Sides of similar triangles are proportional Therefore, π«π·/π«π¬=π·πΈ/π¬π Since we know DP and PE, putting DE = DP + PE π·π/(π·π + ππΈ)=ππ/πΈπΉ Putting DP = 50 cm and PE = 70 cm 50/(50 + 70)=ππ/πΈπΉ 50/120=ππ/πΈπΉ 5/12=ππ/πΈπΉ π·πΈ/π¬π=π/ππ
