Please list as brainlist so that I can level up! Thank You!

Hope this helps!!!!!!!!

Step-by-step explanation:

angle 1 and 2 add up to 180 degrees

3x+2x-25= 180

Answer:

x = 41

Step-by-step explanation:

Supplementary angles sum to 180°, thus

∠ 1 + ∠ 2 = 180 , substitute values

3x + 2x - 25 = 180 ( add 25 to both sides )

5x = 205 ( divide both sides by 5 )

x = 41

(You forgot to provide the choices!?!)

A.) Cos Z = b/c

B.) Sin X= c/b

C.) Tan X = b/a

D.) Tan Z = a/b

B is the answer, Sin X = c/b is wong because Sin X= b/c ( sin = opposite/ hypotenuse)

A cone shaped paper water cup has a height of 12 cm and a radius of 6 cm. If the cup is filled with water to half its height, wh

monitta

Answer:

The portion of the volume of the cup that is filled with water is $\frac{1}{8}$

Step-by-step explanation:

step 1

Find the volume of the paper water cup

The volume of the cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

we have

$r=6\ cm$

$h=12\ cm$

substitute

$V=\frac{1}{3}\pi (6)^{2}(12)$

$V=144\pi\ cm^{3}$

step 2

If the cup is filled with water to half its height, find out what portion of the volume of the cup is filled with water

Remember that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

In this problem the similar cone has half the height of the complete cone

The scale factor is equal to 1/2

therefore

The volume of the cup that is filled with water is equal to the volume of the complete cup by the scale factor elevated to the cube

$V=(1/2)^{3}(144\pi)=(1/8)144\pi\ cm^{3}$

therefore

The portion of the volume of the cup that is filled with water is

$\frac{1}{8}$
