if they're both parallel to a third line that means lines1 and 2 must be parallel to each other, so true

huh the postulate normally assumes that you know the lines are parallel we don't know that yet, so we are stating that 2 is congruent to 6 6 is congruent to 8 therefore 2 is congruent to 8 which should be the transitive property

hm, not quite, 6 and 12 are not corresponding angles (they would have to be in the same position and orientation) notice how 6 and 12 are on the outside side of the parallel lines, making them interior or exterior?

princeevee:

exterior

x=41

hm x = 41 right so CE = 285 CD = 2*CE = 570 to account for both sides of the rectangle 570 + 570 = 1140 applying this same logic to AE AE = 169 AB = 2*169 = 338 338 + 338 = 676 so 1140 + 676 = 1816 (A)

since the end of the fence makes 90 degree angles w/ the sides of the fence by definition the sides of the fence are perpendicular to the end fence so B can't be the solution (we are looking for a false statement) any other ideas?

3 weeks ago
princeevee:

A?

3 weeks ago
Vocaloid:

if the rows of crops are parallel to the sides and the sides are perpendicular to the end of the fence therefore the rows of crops are perpendicular to the end of the fence making A a true statement so it cannot be the solution

3 weeks ago
Vocaloid:

let's look at statement C the original problem never states that rows of crops are parallel to the sides of the fence making C the solution

hm, not quite AE is 169 but it's asking for CD we solved that x = 41 right? so CD = 5x + 80 + 7x - 2 = ?

princeevee:

570

good so 570 = your sol'n

because <1 and <2 are in the same orientation with respect to the transversal they are ~corresponding angles~

hm not quite to find the y-intercept, let x = 0 and solve for y in 3x + 4y = 12

4.

3(0) + 4y = 12 4y = 12 y = ?

3 weeks ago
princeevee:

8

3 weeks ago
Vocaloid:

4 is being multiplied by y so you have to divide both sides by 4 not subtract

3.

notice how only b crosses (0,0) so only line b can be the correct sol'n
