examples
example 1:ex 1:
Find the hypotenuse of a right triangle in which the length of the legs are $18 cm$ and $\frac{13}{2} cm$.
example 2:ex 2:
Find the angle $\alpha$ of a right triangle if hypotenuse $c = 8 cm$ and leg $a = 4cm$.
example 3:ex 3:
Find the hypotenuse $c$ if $\alpha = 50^{\circ}$ and leg $a = 8$.
example 4:ex 4:
