Best ResponseYou've already chosen the best response.0i don't know i am helping my cousin who is in the 8th grade advanced geometry.. i am in first year college. I dont remember anything from high school but trying to help her.

Best ResponseYou've already chosen the best response.2The vertical angles are equal (oposite angles in two crossed lines), and A straight line totals 180 degrees

Best ResponseYou've already chosen the best response.2two variables x and y are to be found, you need AT Least 2 equations to do that

Best ResponseYou've already chosen the best response.2then use one of those for j, and the expression for k, and recall the total of those will be a straight line, j+k=180 so the second equation can be dw:1443150968106:dw

Best ResponseYou've already chosen the best response.2solve 13y + (8x+y) = 180 and 13y = 20x + 3y for x and y

Best ResponseYou've already chosen the best response.2you got it? look over vertical angles, alternate interior angles, corresponding angles, supplimentary angles....think that is it

Best ResponseYou've already chosen the best response.2not sure, lets see 13y + (8x+y) = 180 and 13y = 20x + 3y  14y + 8x = 180 10y = 20x

Best ResponseYou've already chosen the best response.2You can solve it a few ways, but doing substitution, you can solve one of them for either x or y, then replace that into the other equation.... Solving the second for y y = (20/10)*x = 2x so y=2x sub that y value into the other equation

Best ResponseYou've already chosen the best response.214y + 8x = 180 14*(2x) + 8x = 180 left with one variable to solve for now, 28x + 8x = 180 36x = 180 x = 5

Best ResponseYou've already chosen the best response.2now you know what x is, put that into any of the equations involving x and y and solve for the corresponding y value

Best ResponseYou've already chosen the best response.2If you are studying advanced geometry, the concept here is to recognize which angles are equal for parallel lines that are cut by a transversal, how to solve a system of equations in 2 variables was algebra.

Best ResponseYou've already chosen the best response.0thank you sir. although i am not taking it.. i am helping out my cousin. the last time i took geometry was three years ago.
