Can anyone help find the angles of 4 and 7

angles 1 and 3 are 30

angles 5, 8, 10 and 12 are all 85

angle 11 is 95

angles 9 and 6 are 30

7 and 4 are 65

Step-by-step explanation:

angle 2 is congruent to 150, so 1 and 3 are: 360 degrees -150-150=x/2 to get the angles, then cos its an isosceles triangle due to the parallel lines, 9 and 6 are congruent to 1 and three, and 11 is 95 so you do 360 degrees-95-95=x/2 to get 85, then you take the 95 that is congruent to the angle group below it, and subtract 30 cos angles 9 and 4 are equivalent to the whole angle of 11, so yea u subtract 30 and you get 65, and you match up the congruent ones lol hope this helps ik its confusing

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.
