Sin D= opp./hyp. = 35/37
cos D= adj./hyp. = 12/37
tan D= opp./ adj. = 35/12
Area = 1/2 b * h
h = b - 9
b = b
Area = 56cm^2
Area = 1/2 (b - 9) * b
56 = 1/2 (b^2 -9b)
112 = b^2 - 9b
b^2 - 9b - 112 = 0
b = 16 and therefore the height is
h = 26 - 9 = 7
Check
Area = 1/2 * 16 * 7
Area = 8 *7
Area = 56 which checks.
