Answer:
x = -4 3/5
y=2 1/3
Step-by-step explanation:
you need to get these variables alone on each side to find the answer.
This is a 30-60-90 triangle. In a 30-60-90 triangle, the longer leg is √3 times longer than the shorter leg, and the hypotenuse is twice the length of the shorter leg.
Longer leg: shorter leg * √3
Hypotenuse: shorter leg * 2
In the diagram, the shorter leg would be 18/2 = 9. x is the longer leg, so x would be 9√3. y is the hypotenuse, so y would be 9*2 = 18.
x (longer leg) = 9 * √3
y (hypotenuse) = 9 * 2 = 18

Answer:
See graph
Step-by-step explanation:
The red graph is y = 2 sin x where the blue section represents one cycle where 0≤∅≤2π where ∅ is measured in radians.
Answer:
In general, to round to a certain place value, look at the digit to the right of that place value and make a decision. Example: 5.1837 to the nearest hundredth would be 5.18 (round down since 3<5 ), but to the nearest thousandth, it is 5.184 (round up because 7≥5 ).
