Answer:
Step-by-step explanation:
Remark:
It looks to me like the transversal is drawn so that it bisects < L -- the part of L that is part of the red stop sign.
So the first job is find out how big is <L
The total of all angles of the stop sign can be found using
(#sides - 2) * 180
Sides = 8
(8 - 2)*180
6* 180 = 1080
Now the angle between two consecutive sides is 1080/8 = 135
Bisected the bisected angle becomes 135/2 = 67.5
I + L = 180 The two angles rest on the same straight line.
L=67.5
I + 67.5 = 180 Subtract 67.5 from both sides.
Answer: 180 - 67.5 = 112.5
