Answer:
let the ratios be x so, numbers are 2x and 3x
2x+3x+90=180
5x +90 =180
5x=180-90
5x =90
x=90/5
x=18
so, numbers are 36 and54

Answer:
By angle sum property, ∠A+∠B+∠C=180
∘
Given that △ABC is rightangled at A
∴∠A=90
∘
∴∠B+∠C=180
∘
−∠A=180
∘
−90
∘
=90
∘
Given that ∠B:∠C=2:3
Let ∠B=2x and ∠C=3x
⇒2x+3x=90
∘
⇒5x=90
∘
⇒x=
5
90
∘
=18
∘
∴∠B=2×18
∘
=36
∘
and ∠C=3×18
∘
=54
∘
Hence the other two acute angles are 36
∘
and 54
