Answer:

7

Step-by-step explanation:

Let us say that y_{1}= 5.5, x_{1}= 11, and y_{2} = 3.5.

\frac{y_{2}}{y_{1}} =\frac{x_{2}}{x_{1}}

\frac{3.5}{5.5} =\frac{x_{2}}{11}

\frac{7}{11} =\frac{x_{2}}{11}

x_{2} =7

I hope this is correct and helps you!

<h3>What is the history of Angkor?</h3>

A dynasty of Khmer monarchs oversaw one of the biggest, wealthiest, and most advanced kingdoms in Southeast Asia's history from the city of Angkor, which served as the country's capital. The kings of Angkor ruled over a region that stretched from the tip of the Indochinese Peninsula northward to modern-day Yunnan province, China, and from Vietnam westward toward the Bay of Bengal from the last decade of the 9th century, when King Yashovarman I made Angkor his home, until the early years of the 13th century. These kings built a number of enormous structures throughout this time period to exalt themselves, their gods, and their capital city. They did this by using the enormous labour and financial resources at their disposal.
