WebMar 31, 2024 · Triumphantly, the teens announced, “But that isn't quite true: in our lecture, we present a new proof of Pythagoras's Theorem which is based on a fundamental result in trigonometry—the Law of Sines—and we show that the proof is independent of the Pythagorean trig identity \sin^2x + \cos^2x = 1.”. Reportedly, the watching mathematicians …
WebJan 2, 2024 · Solution Using the Law of sines, we can say that: sin112 ∘ 45 = sin B 24 0.9272 45 ≈ sin B 24 24 ∗ 0.9272 45 ≈ sinB 0.4945 ≈ sinB Then, we find sin − 1(0.4945) ≈ 29.6 ∘. Remember from Chapter 3 that there is a Quadrant II angle that has sinθ ≈ 0.4945, with a reference angle of 29.6 ∘. So, ∠B could also be ≈ 150.4 ∘.
