Answer:
(0,5) and (1,0)
Step-by-step explanation:
Answer: 30°, 67° e 83°.
Step-by-step explanation: The angles are (2x + 16)/5 , x e x + 16°
Adding all the angles, comes:
(2x + 16)/5 + x + x + 16° = 180° ;
2x + 16° + 5x + 5x + 80° = 900° ;
12x = 900° - 16° - 80° ;
12x = 804°° ;
x = 804°/12 ;
x = 67°
So, the first angle is (2,67 + 16)/5 = 30°, the second is 67° and the third is 83°.
