In all geometry problems, drawing a diagram is most helpful.
The half-side lengths are 5 feet and 12 feet.
By the Pythagorean Theorem, the hypothenuse, or side length of the rhombus is therefore
sqrt(5^2+12^2)=sqrt(169)=sqrt(13^2)
= 13 feet.
See diagram below.
Number 8:
m1 = 120°
m2 = 60°
m3 = 120°
m4 = 60°
m5 = 60°
Number 9:
m1 = 100°
m2 = 70°

Answer:
C
Step-by-step explanation:
- choose any 2 sets of corresponding values and use the formula
( y2 - y1 ) / ( x2 - x1 )
you'll get -3/4
1 gallon = 3.785 liters
Water in pool = 8000 x 3.785
Water in pool = 30,280 liters
Chlorine dosage = 2.5 mg / liter
Chlorine = 2.5 x 30,280
Chlorine = 75,700 mg
To the nearest thousand milligram:
Chlorine = 76,000 mg
