Answer:
Step-by-step explanation:
In triangle ADC,
b+50+60=180(sum of angles of triangle equals 180)
or,b=180-110
▪b=70
also,
In triangle ABD,
angleA = 30+50=80
now,
a+80+60=180(sum of angles of traingle equals 180)
or,a=180-140
▪a=40'
Ans.
11
11+5=16
16/-16=-1
the slope is (1, 2) if that's what you're looking for!
hope this helps, have a nice day:)
