Ответ:
Part A: ΔGBC is similar to ΔPBE
Part B:
Two triangles are similar if they satisfy the Angle-Angle (AA) similarity criteria
∠CGB ≅ ∠PBE given that they are vertically opposite angles
∠EGC ≅ ∠REG given that they are alternate interior angles of two parallel
∠EGC ≅ ∠BGC by reflexive property
∠REG ≅ ∠PEB by reflexive property
∴ ∠BGC ≅ ∠PEB by transitive property
∴ ΔGBC is similar to ΔPBE by Angle-Angle (AA) similarity criteria
Part C:
For the similar triangles ΔGBC and ΔPBE, we have;
BE/BG = PE/GC = PB/BC
∴ PE/400 = 250/350
PE = 400 × 250/350 ≈ 285.71
PE ≈ 285.71
Similarly
BE/450 = 250/350
BE = 450 × 250/350 ≈ 321.43
BE ≈ 321.43
