Ответ:
5° + 75°+ 100° = 180°
10°+ 80°+ 90° = 180°
20° + 60° + 100° = 180°
45° + 45° + 45° = 135°
50° + 50° + 80° = 180°
So D does not represent interior angle measures of a triangle.
Hope this Helps!!
Ответ:
6n + 1 = 4n + 19
Subtract 1 and 4n from both sides to get variables on one side and constants on the other.
6n - 4n = 19 - 1
Combine like terms and solve for n.
2n = 18
n = 18 / 2
n = 9
Angles 1 and 2 are congruent as labeled in the graph.
So angle 2 is also 6n + 1
Plug in for 9 for n
6(9) + 1
54 + 1
55
Option C is your answer.
