which sets of three lengths can be used to form a triangle?

A. 7ft, 5ft, 2ft

B. 6ft, 4ft, 8ft

C. 15cm, 18cm

D. 72 in, 10 in, 90 in

E. 6m, 2m, 12m

F. 6 yd, 21 yd, 25yd

​

Answer:

x = 5

x = -5

Step-by-step explanation:

2x^2 = 50

2x^2 - 50 = 0

2(x^2 - 25) = 0

2(x^2 + 5x - 5x - 25) = 0

2((x^2 + 5x) + (-5x - 25)) = 0

2(x(x + 5) - 5(x + 5)) = 0

2(x - 5)(x + 5) = 0

x - 5 = 0

x + 5 = 0

x = 5

x = -5

Answer:

Bigcity United lost 12 games.

Step-by-step explanation:

Since you know the percentage of games Bigcity United won, first you need to determine the percentage of games that they lose by subtracting the percentage of games they won from 100%:

100%-60%=40%

Now, you know that they lost 40% of the games and you can calculate 40% of the number of games they played last season:

30*40%=12

According to this, the answer is that Bigcity United lost 12 games.

Answer: m3 for the first one

Step-by-step explanation:de

This could take a while, so I'll simply put the answer with the theorem I used to figure it out with.

1) 45° - minor arc; Central Angles/Arcs Theorem

2) 180° - semi circle; Diameter Theorem? (Whichever theorem states that the diameter separates a circle into two 180° semi circles)

3) 75° - minor arc; Angle Addition Postulate

4) 105° - minor arc; Angle Addition Postulate

5) 225° - major arc; Angle Addition Postulate

6) 45° - minor arc; Vertical Angles Theorem

7) 135° - minor arc; Angle Addition Postulate

8) 240° - major arc; Angle Addition Postulate

9) 315° - major arc; Angle Subtraction Postulate, i think? lol.

10) 180° - semi circle; Diameter Theorem or whatever it's called lol.

Additionally, I determined whether or not an angle was a major arc, minor arc, or semi circle with the knowledge that:

Answer:

the answer is c. 9

Step-by-step explanation:

20=2x+2

18=2x

x=9

Answer:

C

Step-by-step explanation:

Given f(x) = 2x + 2 and f(x) = 20, then equate right sides, that is

2x + 2 = 20 ( subtract 2 from both sides )

2x = 18 ( divide both sides by 2 )

x = 9 → C

Answer:

5 = side a

3 = side c

angle B = 62 degrees

JK is side b

Use the Law of Cosines to find the length of side b.

b^2 = a^2 + c^2 − 2ac cos(B)

b^2 = (5^2 + 3^2) − ( 2 x 5 x 3) cos(62°)

b^2 = (25 + 9) − 30 x 0.469

b^2 = 34 - 30 x 0.469

b^2 = 34 - 14.084

b^2 = 19.916

b = √19.916

b = 4.463

Rounded to the nearest tenth is 4.5 mm.

Step-by-step explanation:

Answer:

∠1 is 33°

∠2 is 57°

∠3 is 57°

∠4 is 33°

Step-by-step explanation:

First off, we already know that ∠2 is 57° because of alternate interior angles.

Second, it's important to know that rhombus' diagonals bisect each other; meaning they form 90° angles in the intersection. Another cool thing is that the diagonals bisect the existing angles in the rhombus. Therefore, 57° is just half of something.

Then, you basically just do some other pain-in-the-butt things after.

Since that ∠2 is just the bisected half from one existing angle, that means that ∠3 is just the other half; meaning that ∠3 is 57°, as well.

Next is to just find the missing angle ∠1. Since we already know ∠3 is 57°, we can just add that to the 90° that the diagonals formed at the intersection.

57° + 90° = 147°

180° - 147° = 33°

∠1 is 33°

Finally, since that ∠4 is just an alternate interior angle of ∠1, ∠4 is 33°, too.

(20,5)

Step-by-step explanation:

20,5=4,1

Answer:

No because they have different slopes

Step-by-step explanation:

(1 , 2) and (2, 4)

Slope:

m=(y2-y1)/(x2-x1)

m=(4-2)/(2-1)

m = 2

Answer:

X=135⁰

Step-by-step explanation:

The sum of angles= 540

Angles are x⁰ x,⁰(x-45⁰),(x-45)⁰

x+x+x+x-45+x-45+x-45=540

5x-135=540   simplify

5x=540+135   Add 135 to both sides

[tex]\frac{5x}{5} =\frac{675}{5}[/tex]

divide both sides by 5

X=135⁰

Answer:

12

Step-by-step explanation:

20-60=12

Answer:

True

Step-by-step explanation:

Z-score may be defined as a position of the raw score in regard to the distance from its mean when it is measured in the units of standard deviation. Z-score is considered as positive, when the values is above the mean. And when it is below the mean, it is considered as negative.

Another name of a z-score is standard score. Z-score can be measured using the relation :

[tex]$z=\frac{x-\mu}{\sigma}$[/tex]

where, z = z-score

           x = raw score

           μ = population mean

           σ = population standard deviation

Thus from the formula we can see how many standard deviation the score is from a men of the distribution by looking at the corresponding z-score.

You know you should multiply, because when working with fractions, decimals, and percentages, the word "of" means multiplied by.

Answer:

x=-5 , y=1

Step-by-step explanation:

-5x-8y=17

x=3.5y-8.5

-5(3.5y-8.5)-8y=17

-17.5y+42.5-8y=17

-25.5y+42.5=17

-25.5y=-25.5

y=1

x=3.5(1)-8.5

x=-5
