Sin θ = 2 / 7
tan θ > 0
cos θ = ?
sin θ = opposite / hypotenuse
tan θ = opposite / adjacent
cos θ = adjacent / hypotenuse
short leg = opposite = 2
hypotenuse = 7
long leg = adjacent = ?
adjacent = √(7² - 2²)
adjacent = √(49 - 4)
adjacent = √45
adjacent = √9 * 5
adjacent = 3 √5
cos θ = adjacent / hypotenuse
cos θ = 3√5 / 7
Answer:
2 balloons = h/4 15 balloons = a/30 10 balloons = c/20 21 balloons = i/42 3 balloons = f/6 4 balloons = k/8 5 balloons = j/10
Step-by-step explanation:
Every time you have a number of balloons, since each costs 2 dollars, you would double the number of balloons to get the price of all of the balloons! Hope this helps! Have a great day!
