Question

The measure of three angle of a quadrilateral is 30 degree and 70 degree and hundred degree find out the measurement of fourth angle ​

Answer 1

Answer:

160°

Step-by-step explanation:

The sum of all angles in any quadrilateral is equal to 360°,. by using this property we proceed

Let unknown angle be "X"

70°+30°+100°+X = 360°

200°+X = 360°

X = 360°- 200°

X = 160°

Therefore measure of fourth angle is 160°

Hope U understood

Answer 2

Answer:-

Given that,

Measures of 3 angles of a quadrilateral is 30°, 70° and 100°.

We have to find the value of the 4th angle.

We know that,

Sum of interior angles of a quadrilateral is 360°

So,

4th angle=360°-(30°+70°+100°)

=360°-200°

=160°

Hence, the value of the 4th angle is 160°.
