Question

In a quardilateral ABCD the measure of the three angle A,B and C of the quardilateral are 110,70 and 80 respectively . Find the measure of fourth angle

Answer 1

360-(110+70+80)=100 this is a simple question

Answer 2

Hey mate !

Here is your answer....

The sum of the measures of the interior angles of a quadrilateral is 360°. Since three of the four angle measures are given, we can find the fourth angle measurement.

Angle ( A+B+C+D ) = 360 degree
110 degree + 70 degree + 80 degree + angle D = 360 degree
Angle D = 360 degree - (110 degree + 70 degree + 80 degree )
Angle D = 360 degree - 260 degree
=100 degree
Therefore , the measure of the fourth angle will be 100 degree.

Hope it helps u !!!
