How long is each side, to one decimal place? Label the length on the diagram. a) side CA B 55° 6.7 cm b) side PQ 35° 3.7 cm R sin 55° = sin 55° = = X sin 55° = CA = CA = So CA = cm, to one decimal place. cos 35° = cos 35° = opposite hypotenuse CA PQ X.cos 35° = PQ = PQ = adjacent hypotenuse PQ cos 35° So PQ = cm, to one decimal place.
