    First we can take the ratio 2:3 as 2y and 3y , It is a linear pair so angle a + angle b=180° 2y+3y=180° 5y=180° y=180°/5 y= 36° Hence y=36°, 2y=2(36)= 72° 3y=3(36)=108° Hence the angles are 72°and 108°.

    Let the angle a be 2x and b be 3x Sum of linear pair =180° a+b=180° 2x+3x=180° 5x=180° x=180°/5 x=36° The measure of a and b are 2×36° and 3×36° 72° and 108°.
