50 POINTS AND BRAINLEST IF YOU CAN GET IT IM HAVING SO MUCH TROUBLE WITH THIS IVE BEEN WORKING ON IT FOR 3 DAYS AND STILL CANT FIGURE IT OUT

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.

Parallelogram GRPC with point B between C and P forming triangle GCB where GC equals 400 ft, CB equals 350 ft, and GB equals 450 ft, point E is outside parallelogram and segments BE and PE form triangle BPE where BP equals 250 ft.

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)

Answers and Step-by-step explanations:

A.

One pair of similar triangles are ΔGBC and ΔEBP.

B.

∠GBC and ∠EBP are vertical angles, so by definition, they are congruent. We also know that since GRPC is a parallelogram, then opposite sides are parallel, so GC ║ RE. Then, since GE is a transversal of these two lines, ∠CGB and ∠PEB are alternate interior angles. By definition, they are congruent.

Thus, by the Angle-Angle Similarity Theorem, ΔGBC ~ ΔEBP.

C.

Similar triangles have the property that corresponding sides have the same ratio. Here, GB corresponds to EB, BC corresponds with BP, and GC corresponds to EP.

We know that BC / BP = 350 / 250. So, this ratio is equivalent to GB / EB and GC / EP:

GB/EB = GC/EP = 350/250

GB = 450 and GC = 400, so:

450/EB = 400/EP = 350/250

Solve for EB and EP separately:

450/EB = 350/250

350EB = 112500

EB = 2250/7 ft

400/EP = 350/250

350EP = 100000

EP = 2000/7 ft

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
