Given ∠4 = 48
∠5 = ∠4 = 48°
∠3 = 180 - ∠4 = 180 - 48 = 132°
∠2 = ∠3 = 132°
∠1 = 180 - ∠2 = 180 - 132 = 48°

Answer:

m∠1=48

m∠2=132

m∠3=132

m∠5=48

Step-by-step explanation:

Hello

1 step

define

When two or more lines are crossed by another line, the angles in matching corners are called Corresponding Angles,according to this concept and ti the graph we can deduce

m∠4=m∠5

also

Two Angles are Supplementary when they add up to 180 degrees,in the graph

m∠3+m∠4=180 (3 y 4 are supplementary angles)

m∠1+m∠2=180 (1 y 2 are supplementary angles)

there is a supplementary angle m∠x of 3, such that

m∠x+m∠3=180 (x y 3 are supplementary angles)

again on the graph

m∠x=m∠1

step 2

m∠4=m∠5

m∠3+m∠4=180

m∠1+m∠2=180

m∠x+m∠3=180

m∠x=m∠1

if

m∠4=48

m∠5=48

m∠3=180-m∠4

m∠3=180-48

m∠3=132

m∠x+m∠3=180

m∠x=180-m∠3

m∠x=180-132

m∠x=48

m∠x=m∠1

m∠1=48

m∠2=180-m∠1

m∠2=180-48

m∠2=132

Given the equation f(x)=-2x²+4x+6 find the average rate of change from x=1 and x=2​
emmainna [20.7K]

Answer:

16

Step-by-step explanation:

1) Plug x=1 into equation

f(x) = -2(1)²+4(1)+6

f(x) = -2²+4+6

f(x) = 4+4+6

y = 14

(1,14)

2) Plug in x=2 into equation

f(x) = -2(2)²+4(2)+6

f(x) = -4²+8+6

f(x) = 16+8+6

y = 30

(2,30)

3) Use slope formula (\frac{y2-y1}{x2-x1})

\frac{30-14}{2-1}

\frac{16}{1}

What is the sum of the arithmetic sequence 151, 137, 123,..if there are 26 terms?
ElenaW [278]
First term: a1 = 151
common difference: d = -14 (we decrease by 14 each time, eg, 151-14 = 137)

nth term of this arithmetic sequence is...
an = a1+d(n-1)
an = 151+(-14)(n-1)
an = 151-14n+14
an = -14n+165

This will be used in the formula below

Sn = n*(a1+an)/2
<span>Sn = n*(151+(-14n+165))/2
</span><span>S26 = 26*(151+(-14*26+165))/2 ... replace every n with 26
</span>S26 = -624

The final answer here is choice C) -624

The <u>Pie Chart</u> is the best type of chart that could be used to represent the distribution of this data.

<h3>What is a Pie Chart?</h3>

A pie chart is a type of circular statistical graph used for the representation of a data set. The graph's segments are proportionate to the percentage of the total in each group.  

However, the proportion of each portion of the pie chart is proportional to the number of the group as a whole.

  • The full pie chart represents 100% of the whole, whereas
  • The pie portion represents sections of the total.

Therefore, from the given information contains many data sets, each data can be represented in each portion to make a full Pie Chart.
