1.	If sin[90 - (A+B)] = cosx = cosyfind the value of x and y; if y is the angle C of triangle ABC. (In triangle ABC, A+B=90∘)
Answer» If sin[90 - (A+B)] = cosx = cosy find the value of x and y; if y is the angle C of triangle ABC. (In triangle ABC, A+B= $90^{\circ}$ )

If sin[90 - (A+B)] = cosx = cosyfind the value of x and y; if y is the angle C of triangle ABC. (In triangle ABC, A+B=90∘)

Answer»

If sin[90 - (A+B)] = cosx = cosy

find the value of x and y; if y is the angle C of triangle ABC. (In triangle ABC, A+B= $90^{\circ}$ )
