No.
obtuse angle
A 58-degree angle is an acute angle that is slightly more than half of a right angle (which is 90 degrees). Visually, it appears as a sharp angle, where the two rays diverge from a common vertex. You can imagine it as being a bit wider than a 45-degree angle but not quite as wide as a 60-degree angle. To visualize it, you could use a protractor or create one by marking a point and measuring 58 degrees from a horizontal line.

A chevron (arrowhead) is a quadrilateral with one angle of more than 1800.
An angle measuring more than 90 degrees is obtuse. An angle measuring less than 90 degrees is acute. An angle measuring 90 degrees is right.
No.
Oh honey, that's a cute little angle you got there. A 23 degree angle is called an acute angle, sweetie. It's less than 90 degrees, in case you were wondering. Keep on measuring those angles, darling!

obtuse angle, definitely.
more than a 90 degree angle but less than a 180 degree angle
An angle more than 90o and less than 180o is an obtuse angle. An angle more than 180o is a reflex angle.
Obtuse angle.
