Answer:
It can be solved in many forms
one by replacing each point to see which one satisfy the equation or by using quadratic formula
so the right answer is the fourth one
If you have never used a unit circle, I recommend making one.
R for the following degrees are
30*= 4((3^1/2)/2)^2
60*= 8(2^1/2)(2^1/2)^2
90*= (8((3^1/2)/2))/4
Answer: 9 cm
Step-by-step explanation:
The formula of the area of a square is
A = s²
The ‘A‘ stands for area and the ‘s’ stands for side measure.
Now, since you already know the side measure, it’s 3cm, you just have to put it into the equation.
So, now you have:
A = 3²
A = 9
Therefore, the area of the square is 9 cm.
