Answer 1

@nincompoop

Answer 2

Don't guess. Prove it!!

\(36^{2} = 1296\)

\(1296/4.9 = 264.49\)

\(2\sin(\theta)\cos(\theta) = \sin(2\theta) \implies \sin(\theta)\cos(\theta) = (1/2)\sin(2\theta)\)

Thus, \(100 = 264.49\cdot (1/2)\sin(2\theta) = 132.24\sin(2\theta)\)

Answer 3

umm sorry meant to say 81^2 answer was something else

Answer 4

Don't delete questions. We can also learn from typos. :-)
