Let a,b,c be the sides of the triangle. Make c the longest side. The value of a and b doesn't matter.
a = 9
b = 40
c = 41

The value of a^2+b^2 is
a^2+b^2 = 9^2+40^2 = 1681

The value of c^2 is
c^2 = 41^2 = 1681

Because a^2+b^2 = c^2 for these values, this means that we have a right triangle.

Answer is choice D

Alborosie

Answer:

Step-by-step explanation:

Using the distance formula,

$AB=\sqrt{(-11-(-7))^{2}+(4-8)^{2}}=\sqrt{16+16}=4\sqrt{2}\\AC=\sqrt{(-11-(-4))^{2}+(4-4)^{2}}=7\\BC=\sqrt{(-7-(-5))^{2}+(8-4)^{2}}=\sqrt{4+16}=2\sqrt{5}\\\\$

So the perimeter is $4\sqrt{2}+7+2\sqrt{5}$

Answer:

YZ = 8.5

Step-by-step explanation:

Since RY is an angle bisector then the ratio of the sides of the triangle are equal to the corresponding ratio of the base, that is

$\frac{YX}{YZ}$ = $\frac{XR}{ZR}$ , substitute values

$\frac{11.9}{YZ}$ = $\frac{7}{5}$ ( cross- multiply )

7YZ = 59.5 ( divide both sides by 7 )

YZ = 8.5

We know, Volume of a Sphere = 4/3 πr³
v = 4/3 * 3.14 * 18³
v = 4.186 * 5832
v = 24,416.64 cm³

Volume of a Sphere = 4/3 πr³
v = 4/3 * 3.14 * 12³
v = 4.186 * 1728
v = 7234.56 cm³

Difference = 24,416.64 - 7234.56 = 17182.08

In short, Your Answer would be: 17182.08 cm³

Hope this helps!
