Step-by-step explanation:
Part A:
ΔGBC ~ΔEBPPart B:
The triangles have 3 congruent angles
∠EBP ≅ ∠GBC as vertical angles∠GCB ≅ ∠EPB as corresponding angles∠CGB ≅ ∠EPB as corresponding anglesPart C:
As per similarity rule, the corresponding sides produce same ratio:
CG/PE = GB/EB = BC/BP350/PE = 400/EB = 300/200EB = 400*200/300 = 266.67 ftPE = 350*200/300 = 233.33 ft
