The numbers are 21, 22, 23 and 24.

acute and acute

Let the numbers be l & m . Hence Sum l + m = 12 Sum of the squares is l^2 + m^2 = 90 Hemce l = 12 - m l^2 = ( 12 - m)^2 l^2 = 144 - 24m + m^2 Substitute 144 - 24m + m^2 + m^2 = 90 2m^2 - 24m = -54 m^2 - 12m = -27 m^2 - 12m + 27 = 0 Factor (m - 3)(m - 9) =0 m = 3 & m = 9 are the two numbers.
