Answer:

∠AEC = 105°

Step-by-step explanation:

If two chords intersect each other in a circle then the vertical angles formed are equal.

In this question two chords AB and CD intersect each other at point E then ∠DEB and ∠AEC are vertical angles which are equal.

Therefore ∠DEB = ∠AEC

Here m∠DEB = 105°

Then m∠AEC = 105° ( by Theorem)

Therefore the correct answer is ∠AEC = 105°

Answer: The measure of angle AEC is 105°.

Step-by-step explanation: Given that in the circle shown in the figure, AB and CD are two chords intersecting at the point E.

And, m∠DEB = 105°.

We are to find the measure of angle AEC.

We can see from the figure that

∠DEB and ∠AEC are vertically opposite angles.

Since the measures of vertically opposite angles are equal, so we must have

$m\angle DEB=m\angle AEC.$

Since, m∠DEB = 105°, so we get

m∠AEC = 105°.

Thus, the measure of angle AEC is 105°.

John has a cylindrical propane tank that measures 8" in diameter and 8" tall If John

kirza4 [7]

Answer:

2 times as large

Step-by-step explanation:

For the original cylinder, we can say that the volume of a cylinder is equal to V= πr²h. For this cylinder, we can say that V = π * radius² * height. The radius is equal to 1/2 of the diameter, so the original radius is 8/2 = 4. Therefore, the volume of the original cylinder is V = π * radius² * height = π * 4² * 8 = π * 16 * 8 = π * 128

For the new cylinder, "twice as wide" means that the diameter is twice as big as the original one. Half the height means that the height is halved. The new diameter is therefore 8 * 2 = 16 (meaning that the new radius is 16/2=8) while the new height is 8/2 = 4. The new volume is thus

V = π * radius² * height = π * 8² * 4 = π * 64 * 4 = π * 256

To see how much larger the new tank volume is, we can divide (new tank volume) by (old tank volume), resulting in

π * 256 / (π *128) = 2

Please provide your work for your answer, the answer is not much important, the work that led to the answer is what matters the

Answer:

It gives you 28 different 10-digit numbers

Step-by-step explanation:

The leftmost position digit can not be 0 --- hence, it is 1, since there is no other possibilities.

The rightmost position (the "ones" position) must be 0 to provide an even number.

Hence, you have 8 remaining positions to fill with six ones and two zeros by an arbitrary way.

You can place two digits of zero among 8 positions by $\frac{C 2}{8}$ = $\frac{8=7}{2}$ different ways = 4*7 = 28 different ways,

Calculate the perimeter of this shape.<br> 12 cm<br> 18 cm

Lisa [10]

Answer:

$12 +18 + x+y + z +w$

In this special case we know that $x+y =12$ and $z+w =18$ and for this case we can add all the values 12+18 +12+18=60 and that represent the perimeter

Step-by-step explanation:

For this case we know that the perimeter is given by:

$12 +18 + x+y + z +w$

In this special case we know that $x+y =12$ and $z+w =18$ and for this case we can add all the values 12+18 +12+18=60 and that represent the perimeter
