Anything with a zero denominator is undefined.
570 - 280
= 290
568 - 276 = 292
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°
Translate the words into math and solve for x. Any questions let me know.
