I don’t understand if this is a math problem or a statement.
To get your answer, you would divide your distance by your speed. You should be going about 1.4 miles per hour.
D+100+40=180
d=180-100-40=40 (sum of all angles)
e= 100+40= 140 (exterior angle)
180-140=40
C+50+40=180
C=180-50-40= 90 (right angle)
A=50
B=180-90-50= 40
