Answer:
Answer c: ![m(x2 - x1) + y1 = y2](https://tex.z-dn.net/?f=m%28x2%20-%20x1%29%20%2B%20y1%20%3D%20y2%20)
Step-by-step explanation:
Hi there!
Let´s start writting the formula
![m = \frac{y2 -y1}{x2-x1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By2%20-y1%7D%7Bx2-x1%7D)
If we multiplicate both sides by (x₂ - x₁):
![m(x2 - x1) = y2 - y1](https://tex.z-dn.net/?f=m%28x2%20-%20x1%29%20%3D%20y2%20-%20y1)
Then if we add y₁ to both sides of the equation:
![m(x2 - x1) + y1 = y2](https://tex.z-dn.net/?f=m%28x2%20-%20x1%29%20%2B%20y1%20%3D%20y2%20)
Then, the right answer is the answer c)
Have a nice day!
Step-by-step explanation:
Therefore the third side should be less than 12+15 = 27cm
And also the third side cannot be less than the difference of the two sides
Therefore, the third has to be more than 15-12 = 3cm
Thus, the third side could be the length more than 3cm and less than 27cm.
Hopefully this was good enough
Answer:
13
Step-by-step explanation:
3b + 8b + 37° = 180° (angle sum property of a triangle)
11b + 37° = 180°
11b = 180° - 37°
11b = 143
b = 143/11
b = 13
hope u understood:))
