Here is a table of the transformation of all four points:

P(-7,0)-> P'(-0,-7) =P'(0,-7)

A(-4,2)-> A'(-2,-4) 

R(-3,0)-> R'(0,-3)

K(-6,2)-> K'(-2,-6)

The initial and rotated images are shown attached.

Angle JKL is 54 degrees. What is the measure of angle MKL? *
hoa [83]

Answer:

MKL = 36°

Step-by-step explanation:

(3x + 6) + (6x + 12) = 54°

3x + 6x + 6 + 12 = 54

9x + 18 = 54

9x = 54 - 18

9x = 36

x = 36/9

x = 4

MKL = 6x + 12

MKL = 6(4) + 12

MKL = 24 + 12

MKL = 36°

Each basket at the farm stand holds 3 pounds of potatoes or 6 pounds of tomatoes. If there are 21 pounds of potatoes and 6 pound
jolli1 [7]

Answer:

8 baskets

Step-by-step explanation:

Well, we can simply divide each number by the amount of vegetables are needed.

6/6=1. We only need 1 basket for tomatoes.

21/3=7. We need 7 baskets for potatoes.

7+1=8 We need 8 total baskets.

Hope this helps! :D

Can anyone explain how you got the answer please.
Ipatiy [6.2K]

Answer:

Option A

Step-by-step explanation:

The first thing we want to do here is identify whether or not the diagonals are perpendicular, which helps much to know to prove what angle AOB.

_____

Let us say that this is a rhombus. That would make the diagonals perpendicular, and hence ∠AOB should be 90 degrees, but let's not jump to conclusions. We need to calculate the length of BO. By Pythagorean Theorem it should be the following length -

( BC )^2 = ( BO )^2 + ( OC )^2,\\( 10 )^2 = ( BO )^2 + ( 7.8 )^2,\\100 = BO^2 + 60.84,\\BO^2 = 39.16,\\\\BO = ( About ) 6.26\\

_____

Knowing BO, to prove that this is a rhombus we can find the length of BO another way, and match it to the length 6.26 -

Δ ABD = Equilateral,

BD = 10 cm,

" Coincidence Theorem " - BO = 5 = OD.

Here BO = 5. 5 is close to 6.26 but not exactly, so the measure of angle AOB is not 90, but better yet 80.
