Question

three angles of a quadrilateral are 100 degree 50 degree and 50 degree . find the measure of the fourth angle.

Answer 1

Answer:

The sum of angles of quadrilateral is 360°

Step-by-step explanation:

let fourth angle be x

100+50+50+x=360°

200+x=360°

x=360-200

x=160°

Hence fourth angle obtained I.e.160°

Answer 2

Answer:

sum of angle of a quad. = 360

so..let the 4th angle by

100+50+50+x=360

200+x=360

x=360-200

x=160

4th angle of the quad is 160 degrees
