Answer:

  • The smallest angle is 41
  • The second angle is 57
  • The third angle is 2*41 = 82

Explanation:

Givens

  • Let the smallest angle = x
  • The second angle is x + 16
  • The third angle is 2x
  • The total is 180o because all triangles have 180 degrees.

Solution

  • x + x + 16 + 2x = 180
  • 4x + 16 = 180 Subtract 16
  • 4x = 180 - 16
  • 4x = 164 Divide both sides by 4
  • 4x/4 = 164/4
  • x = 41

Answer:

Smallest angle: 41°

Second angle: 57°

Third angle: 82°


Explanation:

Let's call the smallest angle as
x

"while a third angle is twice the smallest": third angle is
2x

"One angle of a triangle measures 16∘ more than the smallest": 2nd angle is
16+x

We know sum of 3 angles in a triangle is 180 degrees, so we can set up the equation and solve for x:


x+(16+x)+(2x)=180\\x+16+x+2x=180\\4x=180-16\\4x=164\\x=(164)/(4)=41

So smallest angle is 41°

The 2nd angle is 16+41=57°

third angle is 2*41=82°
