a) The pair of similar triangles are ΔGBC and ΔBEP

b) The triangles ΔGBC and ΔBEP are similar triangles by the condition of Angle - Angle - Angle.

c) The distance from B to E is 266.67 ft and from P to E is 233.33 ft

How to solve the similar triangles?

Part A:

The pair of similar triangles are ΔGBC and ΔBEP

Part B:

From the figure, In triangles ΔGBC and ΔBEP

=> ∠GBC ≅ ∠PBE [ Vertically opposite angles ]

=> ∠CGB ≅ ∠BEP [ Alternative angles ]

=> ∠GCB ≅ ∠BPE [ Alternative angles ]

From the above information, the triangles ΔGBC and ΔBEP are similar triangles by the condition of Angle - Angle - Angle

Part C:

Since the triangles, ΔGBC and ΔBEP are similar the ratio of corresponding angles will be equal.

=> BC/BP = GB/BE = GC/PE

From the given figure,

=> 300/200 = 400/BE = 350/PE

Take 300/200 = 400/BE

=> 3/2 = 400/BE

=> BE = 400(2)/3

=> BE = 266.67 ft

Take 300/200 = 350/PE

=> 3/2 = 350/PE

=> PE = 350(2)/3

=> PE = 233.33 ft

Therefore,

The pair of similar triangles are ΔGBC and ΔBEP

The triangles ΔGBC and ΔBEP are similar triangles by the condition of Angle - Angle - Angle.

The distance from B to E is 266.67 ftand from P to E is 233.33 ft
