In a triangle, the second angle is 5° more than the first angle. And the third angle is three times of the first angle. a) Frame an equation for this information b)Find the three angles of the triangle. (HINT: Sum of measures of three angles of a triangle is 180 degree)Please tell... Do not cheat...

Answer»

ANSWER:

Step-by-step EXPLANATION:

  • let the first angle be x
  • let the second angle be x+5
  • let the third angle be 3x
  • the sum of angles of triangle is 180°
  • x+x+5+3x=180
  • 5x+5=180
  • 5x=180-5
  • x=175/5
  • x=35
  • x+5
  • =35+5
  • =40
  • 3x
  • =3*35
  • =105
