1 and 2 are vertical angles. If m_1 =
(6x + 11) and m2 = (10x - 9), find m1.

x=5

Step-by-step explanation:

You have to put them together 6x+11=10x-9 then you can either subtract 6x or 10x. It would be easier to subtract 6x from 10x. 11=4x-9, then you would add 9 to both sides, finally you divide that answer by 4. That would be the answer to x.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

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