Question

Please look at the attached image.

Answer 1

1 and 3 are 52 degrees

To find angle 3, angle 6 is given as 128 degrees then we know that the opposite angle is supplementary, and the opposite angle happens to be angle 3 so, 180 - 128 = 52 3 = 52

To find angle 1 we use the opposite diagonal property which states that opposites of a diagonal are equal, therefore we can conclude 3 = 1 Which means 1 = 52

Answer 2

Both angle 1 and 3 are 52 degrees

Explanation:

if angle 6 is 128, then so are angle 2, 4, and 8.

if angle 2 is 128, and the whole line is 180, then the missing angle (angle 1) must be 52.

angles 1 and 3 are equal
