First make a triangle by connecting the center point of the circle to one of the end points of the chord.
This will make a right triangle. The new formed line is the radius of the circle and will be the hypotenuse of the right triangle too.
Since one of the legs of the right triangle is half the chord, divide the chord in to two.
9.6 / 2 = 4.8
Now we can calculate for the hypotenuse.
Pythagorean theorem states that a²+b² = c²
So
√2.4² + 4.8² = c
√5.76 + 23.04 = c
√28.8 = c
5.4 = c
C is the hypotenuse and the hypotenuse is known as the radius of the circle.
So the radius is 5.4

Answer:
140/70= 2
35/2= y when x=70
Step-by-step explanation:
1. Distributive Property on the left side
2x-24=5x+9
2. Subtract 9 from the right side and do the same on the left side
2x-33=5x
3. Subtract 2x from both left and right sides
-33=3x
4. Divide 3 from Borge left and right sides
-11=x
Answer: x = -11
