Answer:

A, B, C, E

Step-by-step explanation:

It can be seen from the figure that the points A, B, C and D, all are lying in the line t.

=> So that it can be concluded that AC and BC and BD have the slopes which are equal to each other and also equal to the slop of line t

So that all answer A, B, C are true.

In addition, as FD is parallel with x - axis, so that slope of the line t is equal to <em>tan angel FDB </em>

As FDB is the right triangle with BFD = 90°

=> tan angel FDB = FB/ FD (tan of an acute angel in the right triangle = opposite side/ adjacent side)

=> Slope of the line t is equal to FB/ FD

=> Answer E is true

In parallelogram PQRS, PQ =4x+28, QR=x+31, RS = 10X+4. Which of the

Doss [256]

Answer:

Step-by-step explanation:

1) we know that opposite sides of a parallelogram are congruent so

4x+28=10x+4

2) subtract 4 on both sides

4x+24=10x

3)subtract 4x on both sides

24=6x

4)divide by 6 on both sides

4=x

5)substitute for x

length of RS =10(4)+4

length of RD=44

Self storage center is a storage room that is 8 feet long 6 feet wide and 10 feet high what is the volume of the room

Cerrena [4.2K]

Answer:

480 cubic feet

Step-by-step explanation:

Given length of self storage = 8 feet

width of self storage = 6 feet

height of self storage = 10 feet.

Volume of rectangular object is calculated by formula

volume = length * width * height

substituting the value of length , width and height of self storage room in above formula we have

volume of self storage room = 8 * 6* 10 cubic feet= 480 cubic feet

Can you please answer this

jasenka [17]

Answer:

Sum angle of triangle BHD = 180°

36 + 39 + BHD = 180

BHD = 180 - 36 - 39

= 105°

BHD + x° = 180° (straight angle)

105° + x° = 180°

x = 180 - 105

= 75°
