Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus
6x + 1 + 9x - 24 + 5x - 17 = 180, that is
20x - 40 = 180 ( add 40 to both sides )
20x = 220 ( divide both sides by 20 )
x = 11
Hence
∠PTA = 9x - 24 = (9 × 11) - 24 = 99 - 24 = 75°
∠APT = 6x + 1 = (6 × 11) + 1 = 66 + 1 = 67°
∠PAT = 5x - 17 = (5 × 11) - 17 = 55 - 17 = 38°
