There are three steps:
<span>Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).</span>
Sin x = cos (90-x)
90-x = 19
x = 71
The answer is 71 degrees.
Answer:
V = 8,181.23 
Step-by-step explanation:
Unfortunately, we are not given any answer choices to choose from but using the information provided we can find the actual volume of the basketball. A basketball is made in the shape of a sphere and the formula for the volume of a sphere is the following...
V = 
radius of a circle/sphere is half of it's diameter. Since we are provided the diameter size we simply divide it by 2 which would give us 12.5cm. Now we simply plug this value into the formula and solve for V.
V = 
V = 
V = 8,181.23 
False... a ratio equivalent to 2:5 is 4:10
2/5 × 2/2 = 4/10
