The one on the bottom left...........................
K = -18
you can solve for k by simplifying both sides of the equation, then isolating the variable.
109° and 71°
Supplementary angles sum to 180°
let one angle be x then the other angle is x - 38, hence
x + x - 38 = 180
2x - 38 = 180 ( add 38 to both sides )
2x = 218 (divide both sides by 2 )
x = 109
the two angles are 109° and 109 - 38 = 71°
Answer:
The answer is 2 x 2 x 2 x 3 x 9. Hope this helps.
