⟩ In a right-angled triangle, the square of the hypotenuse is twice the product of the other two sides. Then one of the acute angles of the triangle is…A. 450B. 300C. 600D. 150

3 sides are p,q, sqrt(2pq).

now if it is sright-angle then 2pq=p^2+q^2;

cos(angle)=sqrt(p/2q);

sin(angle)=sqrt(q/2p);

So sin(2*angle)=2*sin(angle)*cos(angle);

sin(2*angle)=1;

So angle=45;
