z° = 80° (Being corresponding angles)
y° + 80° = 180° (Being linear pair of angles)
=> y° = 180° - 80°
=> y° = 100°
x° = y° (Being interior opposite angles)
=> x° = 100°
S = 2b + ph
Lets subtract both sides by 2b
s - 2b = ph
Now, divide both sides by h
(s-2b)/h = p
Hope this helps!
Multiply both sides by <span>cos</span><span>

Answer:
Explained below.
Step-by-step explanation:
The formula for average rate of change is:

1.
=
=
=
= 70
2.
=
=
=
= 35
3.
=
=
=
= 60
4.
=
=

= 20
5. Their average speed was the greatest during the first to second hour.
6. Their average speed was the least during the eight to tenth hours.
7.
=
=
=
= 38.89 or 38.9
