Question

Stuck here, help is greatly appreciated

Answer 1

Angle 2 = 0

angle 6 = 80

angle 9 = 100

angle 15 = 100

angle 16 = 80

Explanation:

2 side by side angle should add up to 180 degrees

So, angle 1 + angle 2 = 180

100 + angle 2 = 180

angle 2 = 80 degrees

angle 3 is equal to angle 7 because of parallel lines

Angle 7 will also equal 100, and angle 6 is right beside it.

Angle 6 + angle 7 = 180

angle 6 = 80

Angle 9 and angle 15 are all equal to 100 because of parallel lines

Angle 16 + angle 15 = 180

Angle 16 = 80

Answer 2

b) 80 because they form a straight line which always has an angle measure of 180
d) 80
e) 100
f) 100
g) should be 80
