Question - Calculating Sum of Angles in a Pentagonal Pyramid
Solution:
The image shows a pentagonal pyramid with its base ABCDE and with the apex labeled as V. The question asks to find the sum of angle C and angle B. There are handwritten notes on the image providing values for angles at base vertices C and B, which are as follows:$$ \angle C = 108^\circ - 36^\circ = 72^\circ $$$$ \angle B = 108^\circ - 36^\circ = 72^\circ $$The sum of $$ \angle C $$ and $$ \angle B $$ would be:$$ 72^\circ + 72^\circ = 144^\circ $$So the sum of angles C and B is $$ 144^\circ $$.
