Question

please tell answers for me

Answer 1

1.exterior angle
2.90 degree
3.180 degree
4.180- 62 = 118 degree

Answer 2

9) The sum of exterior angles of any polygon is 360°

10) One angle = 79°, therefore the other angle: x + 79° = 90°

x = 90° - 79°

x = 11°

11) 1:2

Let the angles be 1x and 2x.

1x + 2x = 180°

3x = 180­°

x = 180°/3

x = 60°

Therefore the angles: 1*60 = 60° and 2*60 = 120°

Measure of the bigger angle is 120°

13) 180°

14) Linear Pair

15) 90°

16) Let x be the other angle.

Let's find the complement angle first.

62° + x = 90°

x = 90° - 62°

x = 28°

Now to find the supplement to 28°

Let the other angle be y.

28° + y = 180°

y = 180° - 28°

y = 152°

17) x = 100° (Vertically Opposite Angles are equal)

y + 80° = 180° (Co interior Angles/Supplementary Angles)

y = 180° - 80°

y = 100°

Hope it helps :)

(PS: Not sure about the 12th one)
