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
