Since the example circle is not shown, I can not answer thoroughly, but I will try my best.
The equation of a circle: (x - h)² + (y - k)² = r², where (h,k) is the center and r is the radius of the circle.
This means that for the radius to be two units, the right side of the equation is 2² = 4. So either B or d can be right.
Depending on the center of the given circle, we could narrow down to our final answer. If the center is (4,5), B is right, and if (5,4) is the center, D is right.
Answer:
Look at 0 next to the dot. It's less than 5. Then round 3.0xxxx to 3.
Step-by-step explanation:
1. By definition, you have:
Sin(α)=Opposite/Hypotenuse
2. Then, SinA is:
SinA=BC/AC
A is the angle in the vertice "A".
BC is the opposite leg to the the angle A.
AC is the hypotenuse of the triangle.
3. By definition, you have:
Cosα=Adjacent/Hypotenuse
4. Then, CosC is:
CosC=BC/AC
C is the angle at the vertice "C".
BC is the adjacent leg to the angle C.
AC is the hypotenuse.
5. Therefore, the answer is the last option:
The equivalent to SinA is CosC
