Triangle area is 1/2bh. If 190 is the base, a quick bit of scaled sketching
yields a height of 110, so area is 0.5(190)(110), or 10450 square units. A
quick bit of trig says that the angle between the 190 and 125 sides is 61.64
degrees, the angle between the 190 and 170 sides is 40.32 degrees, and the
angle between the 170 and 125 sides is 78.04 degrees. Okay, that last one was
easy -- the sum of the three angles in a triangle must equal 180 degrees, so if
you know two of them, the third is what's left.
This has been today's mathematics lesson. :)
