Question

The angles of a quadrilateral are x,(x-10),(x+30) and 2x then the least angle is

Answer 1

hey mate

here is your answer

the sum of the angles of a quadrilateral is 360

thus,

x+x-10+x+30+2x=360

=>5x+20=360

=>5x=340

=>x=68

thus, the least angle is x-10

=68-10

=58(answer)

Answer 2

sum of all Angels in a quadrilateral is 360
x+x-10+x+30+2x=360
5x+20=360
5x=340
x=68
least angle is x-10= 68-10=58
