Find the measure of each of the angles. Don’t forget to label your answer

andriy [413]

Answer:

$a=125^o\\b=55^o\\c=55^o\\d=55^o\\e=125^o\\f=55^o$

Step-by-step explanation:

step 1

Find the value of x

we know that

$(2x+25)^o=(x+75)^o$ ----> by alternate interior angles

solve for x

Group terms

$2x-x=75-25\\x=50$

step 2

Find the measure of angle a

we know that

$a=(x+75)^o$ ----> by vertical angles

substitute the value of x

$a=(50+75)=125^o$

step 3

Find the measure of angle b

we know that

$a+b=180^o$ ----> by supplementary angles (form a linear pair)

we have

$a=125^o$

substitute

$125^o+b=180^o\\b=180^o-125^o=55^o$

step 4

Find the measure of angle c

we know that

c=b ----> by vertical angles

we have

$b=55^o$

therefore

$c=55^o$

step 5

Find the measure of angle d

we know that

d=b ----> by corresponding angles

we have

$b=55^o$

therefore

$d=55^o$

step 6

Find the measure of angle e

we know that

e=a ----> by alternate exterior angles

we have

$a=125^o$

therefore

$e=125^o$

step 7

Find the measure of angle f

we know that

f=d ----> by vertical angles

we have

$d=55^o$

therefore

$f=55^o$

Answer:

$\large\boxed{x^2+8x+19=0\Rightarrow(x+4)^2=-3}$

Step-by-step explanation:

$x^2+8x+19=0\qquad\text{subtract 19 from both sides}\\\\x^2+8x=-19\\\\x^2+2(x)(4)=-19\qquad\text{add}\ 4^2\ \text{to both sides}\\\\x^2+2(x)(4)+4^2=-19+4^2\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\(x+4)^2=-3$

A line is given by the equation 3x + 2y = 4. What is the equation of a line parallel to the given line and passing through the p

Tanya [424]

Answer: B. 3x+ 2y = 12

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

m represents the slope of the line.

c represents the y intercept

The equation of the given line is

3x + 2y = 4

2y = -3x + 4

Dividing through by 2, it becomes

y = - 3x/2 + 2

Comparing with the slope intercept form, slope = - 3/2

If two lines are parallel, it means that they have the same slope. Therefore, the slope of the line passing through (6, - 3) is - 3/2

To determine the y intercept, we would substitute m = - 3/2, x = 6 and y = -3 into y = mx + c. It becomes

- 3 = - 3/2 × 6 + c

- 3 = - 9 + c

c = - 3 + 9

c = 6

The equation becomes

y = -3x/2 + 6

Cross multiplying by 2, it becomes

2y = - 3x + 12

3x + 2y = 12
