Answer:

Choice A.

Step-by-step explanation:

tan < ABC = 60/40

So m < ABC = 56.31 degrees.

This makes m < DBC = 56.31 / 2 =  28.15 degrees

tan 28.15 = DC / 40

DC = 40 tan 28.15

= 21.407 ft.

If the radius of the right cylinder is 5 in and the radius of the oblique cylinder is 4 in, they will have the same volume as lo
steposvetlana [31]

Answer:

False

Step-by-step explanation:

The volume of a right cylinder is given by the formula:

V=\pi r^2h

And the volume if a oblique cylinder is <em>also</em> given by the formula:

V=\pi r^2h

Regardless of the height, if the radius are different, then the volume would not be the same.

Algebraically:

\pi(4)^2h\neq\pi(5)^2h\\16\pi\neq25\pi

TiliK225 [7]

Answer:

This is not the answer this is the trick to find it

Step-by-step explanation:

The points after reflection will follow points equal but different direction, to the path followed before the reflection. So, if the line would cover 3.5 on the x and 5 on the y; it will reflect symmetrically giving you the formula to get your answer.

Find the perimeter of triangle ABC with vertices A(6, 3), B(6, - 2) , and C(- 4, 3) .
anyanavicka [17]

Answer:

26.2 units

Step-by-step explanation:

We are given the points/vertices

A(6, 3),

B(6, - 2) , and

C(- 4, 3)

Step two

Let us find the distances between the given points/vertices

A-B =A(6, 3) to B(6,-2)

d=√((x2-x1)²+(y2-y1)²)

Substitute

d=√((6-6)²+(-2-3)²)

d=√(-2-3)²)

d=√(-5)²)

d=5 units

B-C=B(6, - 2) to C(-4, 3)

d=√((x2-x1)²+(y2-y1)²)

Substitute

d=√((-4-6)²+(3+2)²)

d=√(-10)²+(5)²)

d=√100+25

d=√125

d=11.2 units

C-A=C(-4, 3) to A(6, 3)

d=√((x2-x1)²+(y2-y1)²)

Substitute

d=√((6+4)²+(3-3)²)

d=√(10)²

d=√100

d=10 units

Hence the perimeter is 5+11.2+10

P=26.2 units
