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:
17.0
Step-by-step explanation:
It's a whole number, the decimal goes to the back.
47 because a triangle needs to add up to 180° land you add the 43 plus the 90° and give you 133 and than you subtract the 180 by the 133 and it’s 47
