Answer: 96mm²
Step-by-step explanation:
c=31 mm
m=6mm
b=8mm
d=10mm
l=24 mm
-----------------------
c=31 mm
a=24+6=30 mm
b=8mm
A of ΔM=30*8/2=
120 mm²
A of ΔS=b*m/2=8*6/2=24mm²
Area od shaded triangle is=area of ΔM-area ofΔS=120-24=96mm²
(-5,-10)E
(-5,-3)F
(-3,-10)G
40/2=20
average = 20 miles per hour
Answer:
1 ft
Step-by-step explanation:
From the diagram;

Therefore

Also, AB=8+2=10ft, AD=8ft, AE=4ft. We substitute to get:

Simplify to get:

But AC=AE+EC
This implies that,
5=4+EC
EC=5-1
EC= 1 ft
