Find the measure of angles 1-7 given that lines m and n are parallel and t is transversal.

well here you go

1= 129

2= 51

3= 129

4= 51

5= 129

6= 51

7= 129

Step-by-step explanation:

since angle 51 is congruent to angle 2, they have the same measure which is 51. and if you look at it, angle 1+ 51 = 180 because they are supplementary angles. when you subtract 51 from 180 you get 129. for the other angles, look at the four on the bottom right side as a copy and paste of the four on the top left. basically meaning since 51 is congruent to angle 2 apply that same thing to angles 4 and 6. and since angle 1 is 129, that means angle 3 is 129 also. again, apply that same thing to angles 5 and 7.

sorry if its confusing, i get it

hope i helped :)

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

i believe that the answer is

b. y-1=-2(x-4)

hope this !
