If m∠3 = 54°, find the measure of each missing angle.

Answers

Uisbg multiple line and angle theorems, the values of each of the 14 angles are given.

Using the geometry theorems :

1.)

∠2 is a right angle = 90°

2.)

∠1 + ∠2 + ∠3 = 180° (sum of angle on a straight line)

90 + ∠1 + 54° = 180°

∠1 = (180 - 144) = 36°

(∠2 and ∠5) ; (∠3 and ∠6) ; (∠1 and ∠4) are vertically opposite ;

Hence,

∠4 = 36°

∠5 = 90°

∠6 = 54°

∠3 = ∠8 = 54° (corresponding angles)

∠9 + ∠8 = 180° (sum of angle on a straight line)

∠9 = (180 - 54) =126°

∠7 = ∠9 = 126° (vertically opposite angles)

∠8 = ∠10 = 54° (vertically opposite angles)

∠4 = ∠13 = 36° (corresponding angles )

∠12 + ∠13 = 180° (sum of angle on a straight line)

∠12 = (180 - 36) =126°

∠11 = ∠13 = 36° (vertically opposite angles)

∠12 = ∠14 = 126° (vertically opposite angles)

Final answer:

To find the measure of the missing angles, use the fact that the sum of angles in a triangle is 180 degrees. Substitute the given value and solve for the missing angles. The measure of each missing angle is 126 degrees.

Explanation:

To find the measure of the missing angle, we can use the fact that the sum of angles in a triangle is 180 degrees. Since we know that m∠3 = 54°, and angles 1 and 2 are adjacent angles, we can use the equation:

m∠1 + m∠2 + m∠3 = 180

Substituting the given value for m∠3, we get:

m∠1 + m∠2 + 54 = 180

Now we can solve for the missing angles by rearranging the equation:

m∠1 + m∠2 = 180 - 54

m∠1 + m∠2 = 126

So, the measure of each missing angle is 126 degrees.

Choose the arithmetic series that is associated with this summation.

Answers

Plug n = 1 into the expression 20-9n and we get
20-9n = 20-9*1 = 20-9 = 11

So 11 is the first term of the series that we add up. Therefore the answer must be choice C, which has 11 listed as the first term added

ellen is playing a video game in which she captures butterflies.there are 3 butterflies on screen, but the number of butterflies doubles every minute.after 4 minutes, she was able to capture 7 of the butterflies

Answers

Answer:

Step-by-step explanation:

Ellen is playing a video game in which she captures butterflies.there are 3 butterflies on screen, but the number of butterflies doubles every minute.after 4 minutes, she was able to capture 7 of the butterflies

Initial buttlerfies =3

Since doubles every minute, the no of butterflies follow a geometric progression, with first term =3, and common ratio =2

Hence in 4 minutes no of butterflies = 3(2)^(4-1) = 3(8) =24

So in 4 minutes no of butter flies =24

NO of buttlerflies captured = 7

Remaining butterflies = 17

The image of the point (1, -2) after a rotation of 180° about the origin is:

Answers

Answer:

$(-1,2)$

Step-by-step explanation:

We have been coordinates of a point $(1,-2)$ . We are asked to find the coordinates of the point after a rotation of 180° about the origin.

We know that after rotating a point 180° about the origin, the coordinates of point changes their signs to opposite. The rule of rotating a point 180° about the origin is $(x,y)\rightarrow (-x,-y)$ .

After rotating the point $(1,-2)$ 180° about the origin its coordinates would be:

$(1,-2)\rightarrow (-1,--2)$

$(1,-2)\rightarrow (-1,2)$

Therefore, the coordinates of the given point after a rotation of 180° about the origin would be $(-1,2)$ .

The answer is (-1,2)

What multiplies to 16 and adds to negative 12

Answers

factor 16 and see the - factor pairs and add them, see which add to -12
-1-16=-17 nope
-2-8=-10 nope
-4-4=-8
hmm

we will solve with math
xy=16
x+y=-12
minus x both sides
y=-12-x
sub for y in other equation
x(-12-x)=16
-12x-x^2=16
add 12x+x^2 both sides
0=x^2+12x+16
use quadratic formula
if you have
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^(2)-4ac} }{2a}$

0=x^2+12x+16
a=1
b=12
c=16

x= $\frac{-12+/- \sqrt{12^(2)-4(1)(16) }}{2(1)}$
x= $(-12+/- √(144-64 ))/(2)$
x= $(-12+/- √(80))/(2)$
x= $(-12+/- 4√(5))/(2)$
x= $\frac{-6+/- 2√(5)$
x= $\frac{-6+ 2√(5)$ or $\frac{-6- 2√(5)$

aprox
x=-1.52786 or -10.4721

those are the numbers

the numbes are -1.52786 or -10.4721
