Answer:

A = 125, B = 55, C = 125

Step-by-step explanation:

A line that is cut into two by a line has two angles that equal 180. So angle A + angle D is 180. Angle D = 55 so 180 - 55 = 125. You do the same for every angle but look at the line as being cut into two in different directions for angles a and b and angles c and d.

Find the height of a cone with a volume of 942 cubic units and a radius of 10 units

Dmitry [639]

Volume of a cone: $\frac{1}{3}$ $\pi$ r²h
Plug the radius and volume in the formula.

$\frac{1}{3}$ $\pi$ 10²h = 942
Divide both sides by $\frac{1}{3}$ .

$\pi$ 10²h = 2,826
Divide both sides by pi.

10²h = 900
Divide both sides by 10² (100).

h = 9

The cone's height is 9 units.

if rhombus ABCD were reflected across the x axis to create rhombus A'B'C'D', what would the measure of angle D' be?

Mrac [35]

Answer:

D.64

Step-by-step explanation:

A linear line equals up to 180

A+D=180

Substitute 116 for A

116+D=180

Subtract 116 from both sides

D=64

A reflection across the x-axis won't change the measure of an angle

The answer is 64.

The rectangular floor of a room is 4 feet and 6 inches wide and 8 feet and 3 inches long. How many square yards of floor coverin

siniylev [52]

148.5 square yards of floor covering will be needed to cover the floor.

Step-by-step explanation:

Width of floor = 4 feet 6 inches

Length of floor = 8 feet 3 inches

As we know,

1 foot = 12 inches

Therefore,

Width of floor = 4(12) + 6 = 54 inches

Length of floor = 8(12) + 3 = 99 inches

Area of floor = Length * Width

$Area\ of\ floor=54*99\\Area\ of\ floor= 5346\ in^2$

36 Inch = 1 yard

1 inch = $\frac{1}{36}\ yards$

5346 inches = $\frac{1}{16}*5346 =148.5\ square\ yards$

148.5 square yards of floor covering will be needed to cover the floor.
