A, B, and C are midpoints of ∆XYZ. What is the length of yz
1 answer:
Answer:
Step-by-step explanation:
Comment
When you join 2 consecutive midpoints with a line between them, the length of that line is 1/2 the length of the side opposite the line you just drew.
In other words 24 is 1/2 the length of yz.
Solution
1/2 yz = AB
AB = 24
1/2 yz = 24 Multiply both sides by 2
2(1/2 yz) = 2*24
yz = 48
Answer
yz = 48

<h3>d = 8.6</h3><h3>d = √74</h3>
Step-by-step explanation:
![A (8, 2) = (x_1 ,y_1)\\ B(3,9) = (x_2,y_2)\\\\d = \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\d =\sqrt{\left(3-8\right)^2+\left(9-2\right)^2}\\\\d=\sqrt{(5)^2+(7)^2}\\\\d=\sqrt{25+49}\\\\d=\sqrt{74}\\\\d = 8.6023\\\\d = 8.6](https://tex.z-dn.net/?f=A%20%288%2C%202%29%20%3D%20%28x_1%20%2Cy_1%29%5C%5C%20B%283%2C9%29%20%3D%20%28x_2%2Cy_2%29%5C%5C%5C%5Cd%20%3D%20%5Csqrt%7B%5Cleft%28x_2-x_1%5Cright%29%5E2%2B%5Cleft%28y_2-y_1%5Cright%29%5E2%7D%5C%5C%5C%5Cd%20%3D%5Csqrt%7B%5Cleft%283-8%5Cright%29%5E2%2B%5Cleft%289-2%5Cright%29%5E2%7D%5C%5C%5C%5Cd%3D%5Csqrt%7B%285%29%5E2%2B%287%29%5E2%7D%5C%5C%5C%5Cd%3D%5Csqrt%7B25%2B49%7D%5C%5C%5C%5Cd%3D%5Csqrt%7B74%7D%5C%5C%5C%5Cd%20%3D%208.6023%5C%5C%5C%5Cd%20%3D%208.6)
Step-by-step explanation:
7 + y < 12 it can also be written as
7 + y = 12
y = 12 - 7
y = 5
or
y < 5

Answer:
2x-3y+z
Step-by-step explanation:
-2x-y-2z+4x-2y+3z
combine like terms
-2x+4x= 2x
-y-2y= -3y
-2z+3z= z
so..
2x-3y+z
Answer:
The question is vary small.
Step-by-step explanation:
I can't see it.
Since 19 is a prime number it is not divisible by 2. So its only divisible numbers are 1 and 19 itself. So 19 multiplied by 1 equals 1
