What is the length of DE?

Mathematics
1 answer:
miskamm [114]3 years ago
5 0

Answer:

11

Step-by-step explanation:

If two chords intersect in a circle, the product of the lengths of the segments of one chord equal the product of the segments of the other.

AC *CB = CD CE

4 * (10-4) = CD * 8

4 * 6 = 8 *CD

24 = 8 CD

Divide each side by 8

24/8 = CD

3 = CD

We want the length DE

DE = CD + CE

     = 3 + 8

DE = 11

What is the value of r?<br> Please answer in exact value
sattari [20]
We have three different ways to the solution.

1.
It's a right triangle and <span>isosceles triangle.
The formula of the hypotenuse of this triangle:
h - the hypotenuse
a - the leg

h=a\sqrt2

therefore

r=4\sqrt2

</span>
<span>2.
Use the Pythagorean theorem:

r^2=4^2+4^2\\r^2=16+16\\r^2=16\cdot2\\r=\sqrt{16\cdot2}\\r=\sqrt{16}\cdot\sqrt2\\r=4\sqrt2

</span>
<span>3.
Use trigonometric function:

\sin45^o=\dfrac{4}{r}\\\\\sin45^o=\dfrac{\sqrt2}{2}\to\dfrac{4}{r}=\dfrac{\sqrt2}{2}\ \ \ |cross\ multiply\\\\r\sqrt2=8\ \ \ |\cdot\sqrt2\\\\2r=8\sqrt2\ \ \ |:2\\\\r=4\sqrt2
</span>
