Question:-
The measurement of the three interior angles of a quadrilaterals are: 85 °, 54 ° and 96 °, what is the measurement of the fourth angle?
Answer:-
Given:-
The measurement of the three interior angles of a quadrilaterals are: 85 °, 54 ° and 96 °
To Find:-
The measurement of the fourth angle.
Solution:-
By angle sum property of a quadrilateral,
Sum of all the interior angles = 360 °
So, let the fourth angle be x
85 ° + 54 ° + 96 ° + x = 360 °
235 ° + x = 360 °
x = 360 ° - 235 ° = 125 °
The measurement of the fourth angle is 125 °. [Answer]
