Ihave a test tomorrow & i need to know these, i don't understand how to do it very well

I'm 'just going to explain the bottom right square problem. Well, we know that 6 and 7 make a right angle, and 7 is 66 degrees. That implies that m<6 is 24 degrees. Now, since 3 is the opposite of 6 and 7 together, 3 is also a right angle, which is 90 degrees. We also know that m<2 is 32 degrees. We know that m<2+m<1 equals 90, so m<1 = 58 degrees. For the opposite side 4 and 5, 5 is 32 degrees while 4 is 58 degrees.

So the answers are:

m<1 =58

m<2=32

m<3=90

m<4=58

m<5=32

m<6=24

m<7=66

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
