Question

The measure of three angles of a quadrilateral is 30˚, 70˚ and 100˚. Find out

the measurement of fourth angle.​

Answer 1

Answer:

360 - (100+70+30) = 360 - 200 = 160⁰

Answer 2

Given

The measure of three angles of a quadrilateral is 30˚, 70˚ and 100˚.

We Find

Measurement of fourth angle

We Know that

Sum of angels of quadrilateral is = 360 degree

According to the question

( let the fourth angle is x )

= Sum of angels of quadrilateral is = 360°

= 30° + 70° + 100° + x = 360°

= 200° + x = 360°

= x = 360° - 200°

= x = 160°

Hence , Fourth Angle is 160°.
