Answer: Choice 2 Adjacent and Choice 4 Supplementary

Step-by-step explanation:

Here, we are given four choices, and I will be defining each of them.

  • Vertical angles: two angles that are opposite to each other which was formed by two intersecting lines.
  • Adjacent angles: two angles that share one common vertex and "arm"
  • Complementary angles: two angles that add up to 90°
  • Supplementary angles: two angles that add up to 180°

-----------------------------------------------------------------------------------------------

We can see from the figure given

Both angles are 90°, so ∠1+∠2=90+90=180°

Which is supplementary.

We can see from the figure given

Both angles share a common arm and vertex

Which is adjacent

Hope this helps!! :)

Can someone help with this math problem
katrin [286]

Answer:

20 ft long; 12 ft wide

Step-by-step explanation:

Let   w = the width of the garden

Then l = w + 8

       A = lw

       A = (w + 8)w

=====

The sidewalk is 4 ft wide, so, for the big rectangle consisting of garden plus sidewalk:

Width   = w +8

Length = w + 16

   Area = (w + 8)(w + 16)

=====

The <em>difference</em> between the two areas is the area of the sidewalk (320 ft²).

(w + 8)(w + 16) - (w + 8)w = 320     Factor out w + 8

         (w+ 8)(w + 16 – w) = 320      Combine like terms

                     (w+ 8) × 16 = 320      Divide each side by 16

                             w + 8 = 20        Subtract 8 from each side

                                   w = 12 ft

                                    l = 12 + 8

                                   l = 20 ft

The garden is 20 ft long by 12 ft wide.

The mean of a list of test scores is 80. Adding an additional test score of 92 caused the mean to rise to 82. After this additio
miv72 [106K]

Answer:

6

Step-by-step explanation:

The mean of a list of test scores is 80

Adding an additional test score of 92 caused the mean to rise to 82

To find:

After this additional, how many total test are in the list ?

Solution:

Let the total number of test at first = n

And sum of total score = S

As we know, mean = \frac{sum \ of \ total \ observation}{number\  of \ total\  observation}

                    80= \frac{S}{n} \\

Multiplying both sides by n

80n=S

Now, as adding an additional test score of 92 caused the mean to rise to 82,

S+92=82\times(n+1)\\80n +92 = 82n+82           \  (given \ S =80n)

80n-82n =82-92\\-2n=-10

By dividing both sides by minus ( - )

2n =10

By dividing both sides by 2

n =5

Thus, total number of test at first = n = 5

And, after this additional score added, total number of tests are n+1=6
