62 + 72 = 102
36 + 49 = 100
85 = 100
False.
The Reality:Using the law of Cosines, we find:102 = 62 + 72 - 7(6)cos(x)
100 = 36 + 49 - 42*cos(x)
100 = 85 - 42*cos(x)
15 = -42*cos(x)
-15/42 = -5/14 = cos(x)
arccos(-5/14) is approximately +- 1.9360035481 (rounded up) radians, which is, choosing the only choice, the positive, converting produces arround 110.9o.
