Question

Can the angles ${110}^0,{80}^{\circ },{70}^{\circ }$ and ${95}^{\circ }$ be the angles of a quadrilateral? Give your reasons.

Answer 1

Sum of these angles ${110}^0+{80}^0+{70}^0+{95}^0={355}^0$

But, sum of the angles of a quadrilateral is always ${360}^0$. Hence, ${110}^0,{80}^0,{70}^0$ and ${95}^0$ cannot be the angles of a quadrilateral.
