Question

Vedantu Content Team · Accepted Answer

Hint : Sum of exterior angles is 360.We know that , Sum of all exterior angles of any polygon $ = {360^ \circ }$(a) In figure (a)we have,${125^ \circ } + {125^ \circ } + x = {360^ \circ }$On solving the above equation we get $x$ as $x = {360^ \circ } - {250^ \circ } = {110^ \circ }$Hence the value of $x$ is ${110^ \circ }$.      (b) Similarly we do here in figure (b),$x + {70^ \circ } + {60^ \circ } + {90^ \circ } + {90^ \circ } = {360^ \circ }$On solving we get,$x = {50^ \circ }$Hence the value of $x$ is ${50^ \circ }$.Note : In these types of questions we have to apply properties of exterior angle as the angle we have to find is also exterior. By doing this we can get the correct answer.
