3x + 2x - 20 = 180 5x - 20 = 180 Add 20 to both sides: 5x = 200 Divide both sides by 5: x = 40
No. Since x + (x-1) + 2x = 180 degrees ie 4x - 1 = 180 degrees, if follows that 2x > 90 degrees. So the largest angle is obtuse.
I meant 2x+6
2x 2x to the second
2X divided by 4= 2X
what is 2x + 9 + 62 =180
Assuming that he quadratic is 2x^2 + x - 15, the quotient is 2x - 5.

First of all add all common factors. In par. (2x) + 15 + (2x) = 180 4x + 15 = 180 Divide 4x and 180 by 4. (4x/4) + 15 = (180/4) x + 15 = 45 Then subtract 15 to 15 and 45. x + (15-15) = (45-15) x = 30 Answer is X = 30.

Complementary angles equals 180 degrees. If 3X + 2X = 180, then 5X = 180 so X=36 degrees.
360/2x = 180/x
