Question 145856: In triangle ABC, the length of the altitude to side AB is 6 inches, and the measures of angles A and B are 45 and 60 degrees, respectively. What is the area of triangle ABC? express as a deimal to the nearest tenth.

Drop the altitude and find point D on AC. D cuts AC into two segments.
ABD has a side of 6 and A at 45. So AD is also 6.
BDC has a side 6 with C at 60. So DC is 6 / tan(60) = 3.46
AC = AD+DC = 6+3.46 = 9.46
area of ABC is bh/2 = 6*9.46/2 = 28.4 in^2
