Answer:

140, 60

Step-by-step explanation:

15x+5 + < CDB =180 line form an 180 angle

180-80-6x-6 = < CDB sum of angles in a triangle is 180

substitute < CDB from second to first

15x+5+180 -80-6x-6 =180

combine like terms

9x -81 =0

x=81/9=9

so angle YDC = 15*9+5 = 140 degrees

and angle DBC = 6*9+6= 60 degrees

Solve to find the value of x.

Marianna [84]

Answer:

x = 22

Step-by-step explanation:

triangle = 180 degrees

2x + 12 + x + 54 + 3x - 18 = 180 degrees

combine like terms

6x + 12 + 54 - 18 = 180

6x + 48 = 180

-48 -48

6x = 132

divide by 6

x = 22

Hope this helped! Have a nice rest of ur day! Plz mark as brainliest!!!

Bailey draws a circle on a large piece of paper. Then she cuts out the circle, cuts along the radius of the circle, and tapes th

Andre45 [30]

Answer:

The required equation shows the formula solved for h is $h=\frac{3V}{\pi r^2}$

Step-by-step explanation:

Consider the provided information.

The formula of volume of cone is: $V=\frac{1}{3}\pi r^2h$

Where V, is the volume of the cone with radius, r, and height, h.

Bailey knows the volume and radius of her cone, and she wants to determine the height.

In order to find the height of the cone Bailey need to solve the equation for h.

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

Multiply both the sides by 3.

$3V=\pi r^2h$

Divide both the sides by πr².

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

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

Hence, the required equation shows the formula solved for h is $h=\frac{3V}{\pi r^2}$

Volume of spheres and cones??????????

Inessa [10]

Answer:

The correct answer is option d. 179.503 cub in

Step-by-step explanation:

Formula:

Volume of Sphere = (4/3)πr³

r - radius of sphere

To find the volume of sphere

From the figure we get,

diameter d = 7 in

radius r = d/2 = 7/2 = 3.5 in

Volume = (4/3)πr³ = (4/3) * 3.14 * (3.5)³ = 179.503 cub in

Therefore,the correct answer is option d. 179.503 cub in
