Answer:
x = 15
Explanation:
Since m and n are parallel to the line t.
Then (7x - 10) + (6x - 5) = 180° supplementary angles for a linear pair.
(7x - 10) + (6x - 5) = 180°
13x -15 = 180°
13x = 195°
x = 15
Plug x into the angles to solve for angle.
(7x - 10)
(7*15 - 10) = 105 - 10 = 95°
(6x - 5) =
(6*15 - 5) = 90 - 5 = 85°
