The correct answer is B. Muslim ruler Osman is known for rising from birth among tribal nomads to ruling an empire that eventually spanned three continents.

Explanation:

Osman I was the leader of the Ottoman Turks and the founder of the dynasty, who founded and governed the Ottoman Empire around 1300 AD. The Empire, named after him, would be known as a world empire for more than 4 centuries, until the decline at the beginning of the 18th century. The monarchy was abolished after a period of stagnation and decline on November 1, 1922 and replaced by the Republic of Turkey on October 29, 1923.

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.

a = b-5

c = 2a

a + b + c = 69
