Triangle ΔHIJ is similar to Δ QSR.
Consider the figures supplied.
In ΔQRS
∠Q=53° and ∠R=90°
Therefore,
∠Q +∠R + ∠S = 180°
53° + 90° + ∠S = 180°
∠S = 37°
Consider the HIJ.
In ΔQRS
∠I=37° and ∠J=90°
∠I +∠J + ∠H = 180°
37° + 90° + ∠H = 180°
∠H = 53°
The above computation clearly shows that QRS is identical to HIJ.
As a result, QRS is identical to HIJ.
