I decide: the length and diagonal are given. Find the width of the rectangle.

Given: a=10.5 cm; c=18.2 cm; α=90°(rectangle); b-?

------------

By T. Pythagoras

c²=a² + b²

b²=c²-a²

b=√(c²-a²)=√(c-a)(c+a)=

√(18.2 - 10.5)(18.2 + 10.5)=

√(7.7 * 28.7)=√(7*1.1 * 7*4.1)=7√4.51≈14.8657≈14.87 cm is the answer.

14cm 8.7mm.

How were the mongol invasions of Russia and Persia similar
8_murik_8 [283]

Answer:

D. In both regions mongols helped establish a sucessful road system.

Explanation:

Hello!

In 1220, the army of Genghis Khan invaded the region of Persia and defeated the empire of Chorasmia. Shortly afterwards, the Sharas of Chorasmia, Ala ad-Din Mohamed II died and his son, named Jalal ad-Din Mingburnu, was unable to regain Persia's dominance.  

The Mongols created a system of control and collection of taxes, whose payment was mandatory.

While Altan khan's reign is characterized by declaring Buddhism as the official religion of the Mongol empire, as his predecessors, he allowed freedom of worship.
