Answer:
area = 828.27 cm²
Step-by-step explanation:
add a line from X, perpendicular to WY, call this point A.
angle Y = 180 - 33 - 121 = 26 degrees
sin 26 = XA/49
0.4384 = XA/49
XA = 21.48 which is the height of the triangle
cos 26 = YA/49
0.8988 = YA/49
YA = 44.04
tan 33 = 21.48/WA
0.6494 = 21.48/WA
WA = 33.08
YW = 77.12
(YW)(XA)(0.5) = area
(77.12)(21.48)(0.5) = area = 828.27 cm²
