Question

please solve this problem

Answer 1

$< 1 = < 3$
opposite angles
similarly
$< 2 = < 4$
$< 5 = < 7$
$< 6 = < 8$
since ,
$< 2 = < 6$
$< 1 = < 5$
$< 3 = < 7$
$< 4 = < 8$
therefore,
$< 1 = < 3 = < 5 = < 7 = 5$
$< 2 = < 4 = < 6 = < 8 = 7$
$< 1 + < 2 = 180$
$5x + 7x = 180$
$12x = 180$
$x = 180 \div 12$
$x = 15$
$5x = 5(15) = 75 = < 1 = < 3 = < 5 = < 7$
$7x = 7(15) = 105 = < 2 = < 4 =<6 = < 8$
