Question

in a quadrilateral PQRS angle P is 50 degree, angle q is 60 degree, angle R 60 degree find s .ll. is the quadrilateral convex or concave​

Answer 1

Answer :

angle P =50, angle Q = 60, angle R = 60.

the sum of all angles in a quadrilateral is 360.

Therefore,

P+Q+R+S=360

50+60+60+S=360

170+S=360

S=360-170

S=190

If the diagonals of the quadrilateral is lying inside then the quadrilateral is a convex quadrilateral.

If the diagonal of the quadrilateral is lying outside then the quadrilateral is concave quadrilateral.

Answer 2

Answer:

The answer comes out to be S= 360 degree

Step-by-step explanation:

We know that the sum of the angles of a quadrilateral (4 sided figure) is 360 degree.

Angle P+Q+R=50+50+60= 160 degree

Angle S=360-160=200 degree

Hence, ∠S=200°
