a=2
Answer:
(m1) slope of DE=(7-1)/(10-a)=6/(10-a)
(m2) slope of EF=(11-7)/(7-10)=4/-3=-4/3
since line are perpendicular
m1m2=-1
6/(10-a) ×-4/3=-1
6/(10-a)=3/4
6×4=3(10-a)
24=30-3a
3a=30-24
a=6/3=2
Yes. The left turn from 35B to 6C is 60 degrees.
Answer:
2 miles = 3218.6m
3km = 3000m
ATQ, 2 miles - 3km = 3218.6m - 3000m =
<em><u>218.6m</u></em>
Answer:
x=12
Step-by-step explanation:
2x-8=16(add a to both sides)
2x=24(divide by 2)
x=12
Answer:
