If a triangle has angles measuring 46º , 51º, and 83º, what type of triangle is it?

acute
right
small
obtuse

1 answer

The sum of the angles in any triangle is always 180 degrees. Therefore, in this triangle, the sum of the angles would be 46 + 51 + 83 = 180.

Since none of the angles are equal to or greater than 90 degrees, the triangle is not a right triangle.

The largest angle in this triangle is 83 degrees, which is greater than 90 degrees. Therefore, this triangle is an obtuse triangle.
