Does 514, 684, 855 make a right triangle
Answer:
No, it does not.
Step-by-step explanation:
This does not make a right triangle because in order to have a right triangle you must have 2 of the same numbers.
For example:
900, 800, 900 makes a right triangle
900, 800, 700 does not.

I dont want you guys to get it wrong so it is:BI need help! ABCD is a rectangle.
m<1 =
m<6 =
m<3 =
Answer:
m∠1 = 24°
m∠3 = 66°
m∠6 = 66°
Step-by-step explanation:
They are all near the corners of the rectangle
The corners always equal 90°
But as you can see, they are split down the middle by the X in the rectangle and we have only one angle to go off of; 24°
Since m∠1 is in the same triangle as that angle, and it looks exactly the same, the angle is exactly the same.
m∠3 and m∠6, if you look closely, are also the same. And as I said before, the corners always are 90°. Since 24° is taken from the neighboring triangle, the amount left is 66°, and remember, 24° + x° HAS to equal EXACTLY 90°. So
90 - 24 = 66
So both m∠3 and m∠6 = 66°

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer:
Let's solve your equation step-by-step.
11x − 2x + 15 = 8 + 7 + 9x
Step 1:
Simplify both sides of the equation.
11x − 2x + 15 = 8 + 7 + 9x
11x + −2x + 15 = 8 + 7 + 9x
( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )
( Combine Like Terms )
9x + 15 = 9x + 15
9x + 15 = 9x + 15
Step 2:
Subtract 9x from both sides.
9x + 15 − 9x = 9x + 15 − 9x
15 = 15
Step 3:
Subtract 15 from both sides.
15 − 15 = 15 − 15
0 = 0

Step-by-step explanation:
midpoint formula = [tex](\frac{x_{1} +x_{2} }{2}, \frac{y_{1} +y_{2} }{2})[/tex]
[tex](\frac{14 +13 }{2}, \frac{14 +2 }{2})[/tex] = (13.5,8)
Can someone plzzz helppp meeee!!!!!!!!
Answer:
Radius of the Inner circle:
5.4 is the diameter so find the radius, divide by 2 = 2.7
Next, take pi (3.14) and multiply with the radius (2.7), and use a power of 2.
3.14(2.7)^2 = 22.8906. Then round to the nearest tenth: 23.
Radius of Outer circle:
2.2 is the diameter so find the radius, divide by 2 = 1.1
Next, take pi (3.14) and multiply with the radius (1.1), and use a power of 2.
3.14(1.1)^2 = 3.7994. Then round to the nearest tenth: 4.
Radius of the Inner circle: 23
Radius of Outer circle: 4

Answer:
2/5; 1/2; 2/3; 14/10; 2/6
Step-by-step explanation:
When finding equivalent fractions, multiply or divide both the numerator and denominator by the same number.
4/10 = 2/5 because 4÷2=2 and 10÷2=5
The same thing has been done to both the numerator and denominator (in this case they have both been divided by 2)

A triangle with sides 9, 12 and 15 is similar to a triangle whose longest side is 25. Find the perimeter of the larger triangle.
Answer:
P = 60
Step-by-step explanation:
First, to find the scale factor, or how much bigger the other shape is, you can do so by comparing the two triangles' longest sides.
25 5
---- = ----
15 3
So the larger triangle is 5/3 times bigger.
This means that all of its other sides with also be 5/3 times bigger.
So:
9 (5/3) = 45/3 = 15
12 (5/3) = 60/3 = 20
25 + 15 + 20 = 60
So the perimeter is 60.
You could have also found the perimeter of the smaller triangle, 9 + 12 + 15 = 36, then multiplied it by the scale factor, which would be:
36 (5/3) = 180/3 = 60
You would get the same thing.
