Answer 1

We know that a right triangle have two acute angles.

and we also known that the sum of all angles of the triangle is 180°.

Let the other acute angle be X°
Then,one acute angle be (X-12)°=X°-12°

According to question,

X°+(X-12)°+90°=180°
=>X°+X°-12°+90°=180°
=>2x°+78°=180°
=>2x°=180°-78°
=>2x°= 102°
=>X°=
$\frac{102}{2}$
=51°

Hence, tge other acute angle is X°=51° and (X-12)°=X°-12°=51°-12°=39°


(iii)51°,39° is correct option.
