Need to find value of x and explain how i did it (the method used)

X = 40 degree

Step-by-step explanation:

First I would name the points whatever you do always name the points it really helps

So,

75 = a

50 = b

The middle point will be o

85 = c

X = d

Ok so,

Angle aob = y

Angle cod = z

Now,

75+50+y=180 (angle sum property)

y=180-125

y=55

Angle y = z (vertically opposite angles)

55+85+x=180 ( angle sum property )

x=180-140

Therefore x=40 degree

In higher classes you will be able to do this in your mind itself without calculation all you need is practice.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
