We consider a triangle as in the figure on the right-hand side with

$\alpha=63^\circ,\qquad \beta=56^\circ,\qquad a=1$
Calculate the lengths $b$ and $c$ and the area $O$ of the triangle using a calculator and round to two decimal places.

You may use the below calculator to compute the answer.

$b\approx{}$

(rounded to 2 decimal places)

$c\approx{}$

(rounded to 2 decimal places)

$O\approx{}$

(rounded to 2 decimal places)
