Measure of #Delta ABC# is #color(blue)(61.1822, 70, 85.4595)#

Explanation:

Sum of three angles of a triangle is #180^0#

#/_C = 180 - 45 - 54 = 81^0#

#a / sin A = b / sin B = c / sin C#

#a / sin 45 = 70 / sin 54 = c / sin 81#

#a = (70 * sin 45) / sin 54 = 61.1822#

#c = (70 * sin 81) / sin 54 = 85.4595#
