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:
option c
Step-by-step explanation:
a guitar 15% off means that the cost is now 85%

now the 8% of 170 is


so the total cost is
170+13.6
183.6
The answer would be the
6(3+7)
S+L=155
1.25S+2.50L=265
System of equations...
L=110
S=45
