Answer:

AA similarity theorem

Step-by-step explanation:

we know that

<u>AA (Angle-Angle) Similarity</u> states that  In two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar

In this problem we have that

∠BCA=∠ECD ----> by vertical angles

∠BAC=∠DEC ---> because AB is parallel to ED (alternate interior angles)

therefore

Triangles ABC and EDC are similar by AA similarity theorem

Keith_Richards [23]

Based on the exchange rate and Victor's budget, hector can see the sumo tournament and have about $322 left over.

<h3>How to find cost of Victor's tournament?</h3>

  • Amount with Victor = $380

Conversion rate of US dollars to Japanese yen = 1 : 94.153

  • Cost of the trip = ¥5,488

Ratio of dollar to Yuan

1 : 94.153 = x : 5,488

1/94.153 = x / 5,488

  • cross product

1 × 5,488 = 94.153x

5,488 = 94.153x

x = 5,488 / 94.153

x = 58.2881055303601

Approximately,

x = $58

Amount left with Victor = Total money with Victor - amount spent

= $380 - $58

= $322
