Answer:
We know that the figure has a symmetry
angle 1 = angle 2
angle 1 =180°-(18°+90°) = 180° - 108°=72°
Therefore, <em><u>angle 2 =72°</u></em><em><u>.</u></em>

It would be 13 because you are adding 5 and 8
-8-5b+7+5b
add +5b to -5b to get 0.
-8+7 = -1
Answer is -1.
Angles on a straight line add up to 180°, so:
x + 60 = 180
x = 180 - 60
x = 120°
