PLEASE HELP!!

The diagram below models the layout at a carnival where G, R, P, C, B, and E are various locations on the grounds. GRPC is a parallelogram.

Part A: Identify a pair of similar triangles. (2 points)

Part B: Explain how you know the triangles from Part A are similar. (4 points)

Part C: Find the distance from B to E and from P to E. Show your work. (4 points)

The two triangles are CBG and EBP

They share the same point B, which creates identical angles on each side.

BP is 1/2 of BG so the other sides will be 1/2 of the corresponding sides

PE = 1/2 x CG

PE = 1/2 x 350 = 175

BE = 1/2 x BC

BE = 1/2 x 300 = 150

A) ΔCGB and ΔBPE are similar.

B) They are similar because their corresponding angles are congruent:

C) Given that they are similar, then their corresponding sides are in proportion:

CB/BP = GB/BE

300/200 = 400/BE

BE = 400*2/3 = 266.67 ft

CB/BP = CG/PE

300/200 = 350/PE  

PE = 350*2/3 = 233.33 ft

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
