Question

in the figure lines XY and MN intersect at 0 if angle POY =90°and a:b=2:3 finde c​

Answer 1

Step-by-step explanation:

Let the angles a and b be 2x and 3x respectively.

now,

90+2x+3x = 180

=⟩ 90+5x =180

=⟩ 5x =90

=⟩ x=18

angle a = 2x=2×18= 36

angle b = 3x= 3×18= 54

MN is a straight line. Hence,

angle b +angle c=180

=⟩ 54 + c =180

=⟩ c= 180- 54

=⟩ c= 126 Ans.
