The sum of interior angles of a triangle is always* 180°, so the following triangles are possible:

  • 90°, 40°, 50°
  • 82°, 38°, 60°
  • 59°, 31°, 90°

_____

The following are not possible triangles.

  • 65°, 25°, 75° — add to 165° ≠ 180°
  • 57°, 70°, 33° — add to 160° ≠ 180°

_____

* in plane Euclidean geometry. There are other topologies such that the sum of angles of a triangle differs from 180°.

Write the equation of the line that passes through (2, 3) and is parallel to the line 12x – 5y = 2.
Alexeev081 [22]
         12x - 5y = 2
12x - 12x - 5y = -12x + 2
                 -5y = -12x + 2
                  -5          -5
                    y = 2.4x - 0.4
               y - 3 = 2.4(x - 3)
               y - 3 = 2.4(x) - 2.4(3)
               y - 3 = 2.4x - 7.2
                 + 3           + 3
                    y = 2.4x - 4.2

The faces of a tetrahedron die are numbered 1 to 4. If each of the 4 sides is equally likely to land down, what is the probabili
Marat540 [252]
Hello!

If there is 4 faces and 1/4 chance of any side end up face down, we just have to decrease one chance, so, the chance of  the face "2" does not end up face down is equal the sum of the chances of the others faces end up face down, so, we have: 3/4.

Answer: D:{8,-6,2,0}: R:{5,-9,5,-8}

Explanation:
The domain is x and the range is y, so I'll go through each coordinate;
(8,5) domain=8; range=5
(-6,-9) domain=-6; range=-9
(2,5) domain=2; range=5
(0,-8) domain=0; range=-8
So the answer is D:{8,-6,2,0}: R:{5,-9,5,-8}
