In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
It is given that there are 112 angles of [tex] 1^o [/tex].
All the 112 angles make up [tex] 112*1^o=112^o [/tex].
Clearly each component angle is acute and the total is obtuse since
[tex] 112^o>90^o [/tex].
