1. What were the two major functions of the Ottoman bureaucracy during the Middle Ages?
To build better military units that could not be defeated.
To collect taxes and keep records of everything that happened in the empire.
To provide a precise history of the Empire's efforts at expansion.
To provide a set of laws that all people in the Empire must follow.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
