Answer:

C. AB = 5\frac{5}{7}

Step-by-step explanation:

When two polygons are considered similar, the ratio of their corresponding sides would also be equal.

Since ∆ABC and ∆ADE are similar, \frac{AE}{AC} = \frac{AD}{AB}

\frac{7}{4} = \frac{10}{AB}

Cross multiply

7*AB = 10*4

7*AB = 40

Divide both sides by 7 to find AB

\frac{7*AB}{7} = \frac{40}{7}

AB = \frac{40}{7}

AB = 5\frac{5}{7}

Zepler [3.9K]

Answer:

Peter Jonathan Winston (March 18, 1958 – disappeared January 26, 1978) was an American chess player from New York City

Step-by-step explanation:

In late 1977, Winston attended a FIDE-rated tournament at Hunter College High School in New York City. Despite being one of the highest-rated players in the tournament, Winston lost all nine of his games. A few months later, on January 26, 1978, following further surprising game losses, Peter Winston vanished and was never heard from again. According to some sources, Winston's disappearance occurred when he left his home without money, identification, or luggage during a severe winter storm. Many chess players who were close to or acquainted with Winston claim that the champion chess player's mental health had deteriorated, along with his game performance, in the last few years of his life, and that the decline in his mental health may have led to his disappearance.

2. Given < MCP = 65°, find the measurement of arc MP , arc MRP and < MRP.​
iren2701 [21]

▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪

We know that the Angle subtended by an arc on centre of the circle is double as that of Angle subtended by the same arc on the circumference (boundary) of the circle

So,

  • \sf \angle MCP =  2\angle MRP

  • \sf65 \degree = 2 \angle MRP

  • \sf\angle MRP = 65 \degree \div 2

  • \sf\angle MRP = 32.5 \degree
