3.2 x 10^7 = 32,000,000
4.5 x 10^9 = 4,500,000,000
32,000,000 x 4,500,000,000 = 1.44e17

Answer:
∠A = 26°
Step-by-step explanation:
Supplementary angles total 180°.
∠A +∠B = 180°
(x -16)° +(3x +28)° = 180°
4x° + 12° = 180°
x° +3° = 45°
x° = 42°
∠A = (x -16)° = 42° -16°
∠A = 26°
7 x 13 = 91.......so 91 is not a prime, it is a composite
