\begin{array} { l } { \text { One angle of a quadrilatral measures } 1

1.	\begin{array} { l } { \text { One angle of a quadrilatral measures } 120 ^ { \circ } \text { and } } \\ { \text { rest three angles are of equal measure. Find the } } \\ { \text { degree measure of equal angles. } } \end{array}
Answer» 3x + 120 = 360 3x = 360-120 x = 240/3 x = 80 one angle is 80 second angle is 80 third angle is 80 fourth angle is 120 total 360

Answer»

3x + 120 = 360

3x = 360-120

x = 240/3

x = 80

one angle is 80 second angle is 80 third angle is 80 fourth angle is 120 total 360
