WebA larger side is opposite a larger angle. ANSWER: s = 13.1. Proving the Law of Sines: This proof works with an acute triangle. We start with an oblique (not-right) triangle ABC, with an altitude from C labeled h. (now cross multiply) h = b sin A and h = a sin B. (since both expressions = h) b sin A = a sin B. WebMultiplying both sides times 40, you're going to get, let's see. 40 divided by 30 is 4/3. 4/3 sine of 40 degrees is equal to sine of theta, is equal to sine of theta. Now to solve for theta, we …
