Call the angle v: tan v = opp/ adj = 70/21 = 3.33; tan 73 = 3.26, tan 74 = 3.48 so 73 degrees is nearest. Check: sin73 = opp/hyp so hyp is 70/sin 73 = 70/0.956 = 73.22. Now use Pythagoras: does 73.22 squared equal 70 squared plus 21 squared? In whole numbers 5329 = 4900 + 441? Not quite, but good enough for Wiki!
The square root of 5329 is 73, so 5329 is a perfect square, since it can be both squared and have its square root taken with both results being integers.
73% of 73 = 73% * 73 = 0.73 * 73 = 53.29

3x squared - x squared = 2x squared
Yes, they both are. They are odd, and neither one is divisible by 3, 5, or 7. The next prime is 11, and they are both less than 11 squared (121), so they are prime.
