Find mA and mB.Found 2 solutions by stanbon, MathTherapy:Answer by stanbon(57282)   (Show Source): You can put this solution on YOUR website!A and B are supplementary angles. mA is 6° less than twice mB. Find mA and mB. ---- Let mA = 180-x Then mB = x ------- Equation: 180-x = 2x-6 3x = 186 x = 31 degrees (measure of B) --- 180-x = 180-31 = 149 degrees (measure of A) ----------- Cheers, Stan H. Answer by MathTherapy(1422)   (Show Source): You can put this solution on YOUR website! A and B are supplementary angles. mA is 6° less than twice mB. Find mA and mB. Since the angles are supplementary, then angle B = 180 - A We then have: A = 2(180 - A) - 6 A = 360 - 2A - 6 A + 2A = 354 3A = 354 Angle A = , or Angle B = 180 - 118, or You can do the check!!
