Answer:
C
Step-by-step explanation:
Since CB is a tangent to the circle then ∠ ABC = 90°
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, thus
AC² = 5² + 8² = 25 + 64 = 89 ( take the square root of both sides )
AC = → C
Answer:
Step-by-step explanation:
Assuming the image is the shown below, we can use the following formula to find the length of arc :
Where is the angle in the arc and is the radius of the circle.
Since we are not given the value of , we will only work with this.
For :
For :
We firstly need to find the value of this angle, taking into account the whole circumference is :
Finding :
Now, let's calculate the length of arc:
