Let AB be a chord of the given circle with centre and radius 13 cm.
Then, OA = 13 cm and ab = 10 cm
From O, draw OL⊥ AB
We know that the perpendicular from the centre of a circle to a chord bisects the chord.
∴ AL = ½AB = (½ × 10)cm = 5 cm
From the right △OLA, we have
OA² = OL² + AL²
==> OL² = OA² – AL²
==> [(13)² – (5)²] cm² = 144cm²
==> OL = √144cm = 12 cm
Hence, the distance of the chord from the centre is 12 cm.

The given rational function is
We need to rationalize the denominator by multiplying both the numerator and the denominator by the conjugate of
which is
When we rationalize we obtain:
The denominator is now a difference of two squares:
We apply this property to get
This simplifies to
Or
I believe 24 is the correct answer
Answer:
7^12
Step-by-step explanation:
To divide an exponent by the other exponent, subtract the exponent from the denominator from the exponent above!
14-2= 12
Hope this helps :)
<em>CML is a supplementary angle</em>, it can't be a complementary angle because complentary angles are formed by two angles that equal 90 degrees, a
right angle. CMW is a right angle which is 90 degrees so that plus WML
has to equal more than 90, it must be a supplementary angle which is
formed by two angles that equal 180 degrees.
