Given:
In a right angled triangle ABC the perpendicular and the base measure 3 cm.
To find:
The hypotenuse and three trigonometric ratios.
Solution:
Pythagoras theorem:

Use Pythagoras theorem in triangle ABC.




The three trigonometric ratios are



Similarly,



And,



Therefore, the hypotenuse is
cm and three trigonometric ratios are
.
N+m/p=q
Multiply by p
Np+m=pq
Subtract m
Np=pq-m
Divide by p
N=(pq-m)/p
