Answer:
B) 6.68
Step-by-step explanation:
Use Cosine.
Cosine= Adjacent ÷ Hypotenuse
In this case the base you want to find is adjacent to the angle, 42°. Hence,
Cos (42)= adjacent ÷ hypotenuse
Cos (42) = x ÷ 9
x = Cos (42) × 9. Input that into your calculator.
x= 6.68
To remember the trigonometric ratios/formulas
Use the acronym, SOHCAHTOA
Hope this helps!!!!
Length x Width = Area
In your case, you'd want to flip around the equation.
100+x=900
900 divided by 100 is 9, so your width would be 9 Yards.
Answer:
Step-by-step explanation:
Given that at a hockey game, a vender sold a combined total of 204 sodas and hot dogs.
The number of sodas sold was three times the number of hot dogs sold.
Let no of hot dogs be sold be x then no of sodas sold will be 3x
Total number of sodas and hot dogs 
the number of sodas =153
and the number of hot dogs sold=51
