Answer:
Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication, and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.
Step-by-step explanation:
First you can find angle C:
A - 50 ⇒ 75 - 50 = 25°
should know if you add all the angles in the triangle together you will always get 180 °
so now you can find angle B:
180- ( 75 + 25 ) ⇒ 180- ( 100 ) = 80°
so the measure of angle A is: 75°
the measure of angle B is: 80°
the measure of angle C is: 25°

Rise over run is another term for slope, with we can use to derive a linear equation.
The term rise over run in technical terms is the change of y over the change of x.
To find the rise over run, subtract the y terms and divide that by the x terms.
![\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
You can use this to derive a linear equation as earlier mentioned by plugging in given points.
For example, a line passes through (3,4) with a rise over run of 3.
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
![4=3(3)+b](https://tex.z-dn.net/?f=4%3D3%283%29%2Bb)
![4=9+b](https://tex.z-dn.net/?f=4%3D9%2Bb)
![b=-5](https://tex.z-dn.net/?f=b%3D-5)
So therefore the y intercept is -5, and the equation is ![y=3x-5](https://tex.z-dn.net/?f=y%3D3x-5)
