SUM OF ANGLES IN A QUADRILATERAL IS 360°.

IF 2 ANGLES SUM UP 170°.

HENCE OTHER TWO SUM UP =

$360 - 170$

$= 190 {}^{o}$

Answer 2

we know,

sum of all angles in a quadrilateral are 360°

therefore,

a+b+c+d= 360....( here a, b, c and d are angles)

170+ c+d= 360...(a+b= 170)

c+d= 360-170

c+d= 190

therefore the sum of remaining angles is 190

hope this helps!! ☺☺✌✌
