Question

If three angles of a quadrilateral are 100 , 50 and 50. Find the fourth angle.​

Answer 1

hope this helps you........

Answer 2

The three angles of a quadrilateral are 100,50and 50

consider the fourth angle be x

STEPS

100+50+50+x=360(quadrilateral side has 360°)

200+x=360

x=360-200

x=160

The fourth angle is 160°

EXPLANATION

We find the fourth angle in a quadrilateral when the measurements of three angles of a quadrilateral are known, then subtract the three angles from360° to calculate the missing angle.

Quadrilateral is a closed shape that is formed by joining four points among which any three points are non- collinear. A quadrilateral has four sides ,4 angles, and 4 vertices. quadrilateral is derived from a Latin word.
