Answer:

a. d = $\sqrt{3}$

b. d = $2\sqrt{3}$

c. d = $s\sqrt{3}$

Step-by-step explanation:

to find the length of the longest diagonal of the cube at first you will find the length of the diagonal if its base

If the length of the side of a cube is x

∴the length of the diagonal of the base = $\sqrt{x^{2}+x^{2}}=\sqrt{2x^{2} }=x\sqrt{2}$

Now to find the length of the longest diagonal we will use Pythagoras with the side of the cube and the diagonal of the base

$d^{2}=(x\sqrt{2} )^{2} + x^{2}=2x^{2} +x^{2} =3x^{2}$

$d=\sqrt{3x^{2} }=x\sqrt{3}$

means the length of the side multiply by root 3

a. The length of the side is 1 so $d=\sqrt{3}$

b. The length of the side is 2 so $d=2\sqrt{3}$

c. The length of the side is <em>s s</em>o $d=s\sqrt{3}$

Given AB is a diameter, find the measure of

Sonbull [250]

Answer:

Angle BCA = 90

Step-by-step explanation:

A triangle inscribed inside of a circle using the diameter as it's hypotenuse is a right triangle

Where the angle opposite of the hypotenuse ( or diameter ) is the right angle

Angle BCA is the angle opposite of the diameter

Hence BCA = 90

What property is this?

Soloha48 [4]

Answer:

x= 0/0

Step-by-step explanation:

Let's solve for x.

5x−5z=5(x−z)

Step 1: Add -5x to both sides.

5x−5z+−5x=5x−5z+−5x

−5z=−5z

Step 2: Add 5z to both sides.

−5z+5z=−5z+5z

0=0

Step 3: Divide both sides by 0.

0/0=0/0

Hope this helps ;-))
