Answer:
24 sin 70
Step-by-step explanation:
Sin 70 = 24/ladder
Ladder = 24* sin 70
We are asked to find the area of patio. It is circular so formula used for area is given by:
Where
r = radius = diameter / 2 = 20 / 2 = 10 feet
When we round this to the nearest whole number:
We need to know this:
If Δ > 0 we have two and different solutions
If Δ = 0 we just one solution
If Δ < 0 we don't have real solutions
(2, 0°) is already in polar coordinates, with the smallest possible angle. The radius is 2, always 2. Expressions with variations of the angle are also good representations of (2, 0°) if their angles are all integer multiples of 360 degrees. For example: (2, 720°) represents the same point in polar coordinates as does (2, 0°).
The larger the number is in front of the negative the smaller the number is. Fir example -90 is smaller than -5.
