Answer:

x = 18, ∠ A = 73°

Step-by-step explanation:

∠ A and ∠ B are same- side interior angles and supplementary, sum to 180°, then

6x - 35 + 3x + 53 = 180, that is

9x + 18 = 180 ( subtract 18 from both sides )

9x = 162 ( divide both sides by 9 )

x = 18

Thus

∠ A = 6x - 35 = 6(18) - 35 = 108 - 35 = 73°
