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
13cm is the answer i hope this helps you!!!!!!!
divide 417.12 by 23.7, and get your answer: <u>17.6</u>
<span>
<span>7.4
divided by 185 is 0.04. This means that 7.4 is four percent of 185, which is
seen when we multiply 0.04 by 100 to convert it to a percent.
So the answer is 185 lb ± 4%.</span>
