An Obtuse Angle is more than 90° but less than 180°
A. 2(20)+14=54, This is an Acute Angle, so this can't be one.
B. 2(38)+14=90, This is a Right Angle, so this can't be one.
C. 2(47)+14=108, This is an Obtuse Angle, so this is one.
D. 2(60)+14=134, This is an Obtuse Angle, so this is one.
E. 2(98)+14=210, This is a Reflex Angle, so this can't be one.
The answer is C and D.
