In the given figure, what is value (in degrees) of Q?
Given:
Top angle = 70°
Inner angle = 150°
Bottom angle = 20°
Find Q
Formula Used:
Sum of interior angles of a quadrilateral = 360°
Solution:
Consider the figure as a quadrilateral.
The given inner angle is 150°, but it is an exterior indentation angle.
So the interior reflex angle there is:
360° − 150° = 210°
Now sum of interior angles:
70° + 20° + 210° + Q = 360°
300° + Q = 360°
Q = 60°
Therefore,
Q = 60°
