Answer:

∠CED = 15° .

Step-by-step explanation:

Given : Figure .

To find : What is the measure of ∠CED.

Solution : We have given Two triangle ABC and CDE.

We need to measure of ∠CED.

In triangle CDE , Angle ∠DCE = 90 °.

∠CDE = 75°.

By the angle sum property of the triangle : Sum of all the triangle is 180°.

∠CED + ∠CDE +∠DCE = 180 .

Plug the values

∠CED + 75 + 90 =180 .

∠CED + 165 = 180 .

on subtracting both sides by 165.

∠CED = 180 - 165 .

∠CED = 15° .

Therefore, ∠CED = 15° .

You take 90 + 75 = 165 and then 180 - 165 = 15 degrees so that’s your answer

The diameter of a sphere is 16 cm. What is the sphere's volume? Round to the nearest tenth.

ohaa [14]

Answer:

V ≈ 2144.70 $cm^3$

Step-by-step explanation:

Radius is going to be used instead of the diameter. Half of 16 is 8, and so that will be the value that shall be used.

$V = (4/3)\pi (8)^3$

V ≈ 2144.66 $cm^3$

V ≈ 2144.70 $cm^3$

Calculate the slope of the line passing through the two colored points below. (1,4) (-1,-1)

leonid [27]

Answer:

Slope = $\frac{5}{2}$

Step-by-step explanation:

We can define the slope as the "change in y values" divided by the "change in x values".

By change in, we mean, 2nd point MINUS the first point values.

The points given is:

(1,4) & (-1,-1)

<u>Change in y value:</u>

-1 - 4 = -5

<u>Change in x value:</u>

-1 -1 = -2

Slope is -5/-2 = 5/2

There is no answer choice. The correct answer is 5/2

Look how he has proved that

Advocard [28]

Answer:

false

Step-by-step explanation:

as a guy who studied calculus, a lot of things were done that are just mathematically incorrect. for instance,

infinity - infinity is not 0.

0÷0 is undefined. so you cant just equate it to ( 2 × infinity)

to sum up this proof is entirely false.

if you still have any doubts make sure to ask.

Find the value of the variable.

Nikolay [14]

we are given that

both sides are equal

so, their length must be equal

$HK=\sqrt{(p-1)^2+(5-2)^2}$

$HK=\sqrt{(p-1)^2+9}$

now, we can find other side

$JK=\sqrt{(p-7)^2+(5-2)^2}$

$JK=\sqrt{(p-7)^2+9}$

now, we can set them equal

$HK=JK$

$\sqrt{(p-1)^2+9}=\sqrt{(p-7)^2+9}$

now, we can take square both sides

$(p-1)^2+9=(p-7)^2+9$

now, we can solve for p

$(p-1)^2=(p-7)^2$

$p^2-2p+1=p^2-14p+49$

$-2p+1=-14p+49$

$12p=48$

$p=4$ ..............Answer
