To calculate the distance between 2 points we will use the following equation:
![D=\sqrt[]{(x_2-x_1)^2-(y_2-y_1)^2}](https://tex.z-dn.net/?f=D%3D%5Csqrt%5B%5D%7B%28x_2-x_1%29%5E2-%28y_2-y_1%29%5E2%7D)
For this exercise we have the following data:

We plug the values into the distance equation and solve for the unknown Y
Answer:
2x+12=64; x=26
Step-by-step explanation:
2x+12=64
2x=52
x=26
The name of the angle is obtuse
Answer:
y = -
x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = -
, thus
y = -
x + c ← is the partial equation
To find c , substitute (4, - 5) into the partial equation
- 5 = - 2 + c ⇒ c = - 5 + 2 = - 3
y = -
x - 3 ← equation of line
