Answer 1

`\text{The two angles are supplementary, so their sum is}~ 180^(\circ) \\\\m\angle A + m\angle B =180\\\\\implies 2x-14+3x-6 = 180\\\\\implies 5x -20 = 180\\\\\implies 5x = 180+20\\\\\implies 5x = 200\\\\\implies x =\frac{200}5\\\\\implies x = 40\\\\\text{Hence, the measure of angle A is}~ m\angle A = (2\cdot 40 -14)^(\circ) = 66^(\circ)`
