Which of the following equations could be the line of best fit?
O A. y = x + 100
OB. X = 100
OC. y = x - 100
OD. y = 100

x = 105

Step-by-step explanation:

Skills needed: Triangle Angle Measures, Solving a One-Variable Equation

1) To get the answer, you need to know that all the angles inside a triangle add up to 180 degrees. This is very important in the future as well.

2) So to find x, we can make the equation: x + 30 + 45 = 180

3) You can combine like terms:

30 and 45 can be combined --> 30 + 45 = 75

4) Based on step 3, you can get: x + 75 = 180

Subtract 75 from both sides, and you will get: x = 105

Hope this helps and have a nice day! :] :) :D
