Example Question - calculating angles
Here are examples of questions we've helped users solve.
Finding the Value of x in a Quadrilateral
\begin{align*} \angle CAB + \angle ABC + \angle BCD + \angle CDA &= 360^\circ \\ 32^\circ + 115^\circ + 90^\circ + x^\circ &= 360^\circ \\ x^\circ &= 360^\circ - 237^\circ \\ x^\circ &= 123^\circ \end{align*}
Calculating Sum of Angles in a Pentagonal Pyramid
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 \( 144^\circ \).
