From: Kendra Angles ABC and DBA are supplementary. If m<ABC =x+1 and m<DBA = 2x-6, find the measurement of angle DBA. |

Hi Kendra.
That means that 180 = (2x-6) + (x+1). Re-arrange this equation to solve for x. Then put that value of x into the expression 2x - 6 to solve your question. Hope this helps! |
Supplementary angles add up to 180°. |
