Answer:

The sum of angles is 176° which is less than 180°, hence it is a:

Hyperbolic Geometry

Explanation:

In Euclidean geometry, sum of all the angle of the triangles is equal to a straight line, which means the sum of all angles is equals to 180°

Hyperbolic geometries are Non-Euclidean geometries which strictly has the sum of all angles less than 180°. The difference between the 180° and the sum of angles found is usually known as Defect.

Elliptical Geometries are Non-Euclidean geometries, the sum of angles of the triangle is always greater than 180°

Spherical geometries are also Non-Euclidean geometries which shows a 2-D surface of a sphere. The sum of angles is always great than 180° and less than 540°

There is only 1 valid option i.e Hyperbolic Geometries.
