Answer:second optionStep-by-step explanation:The sum of the 3 angles in a triangle = 180°∠ 1 and 33° form a straight angle and are supplementary, thus∠ 1 = 180° - 33° = 147°----------------------------------The third angle in the triangle on the left is180° - (33 + 47)° = 180° - 80° = 100°, thus∠ 2 = 180° - 100° = 80°--------------------------------------∠ 2 and the angle in the triangle form a straight angle and are supplementary, angle = 180° - 80° = 100°The third angle in the triangle on the right is180° - (100 + 48)° = 180° - 148° = 32°, thus∠ 3 = 180° - 32° = 148° ( straight angle )Thus∠ 1 = 147°, ∠ 2 = 80°, ∠ 3 = 148°
