Solving acute triangles
WebMath 20 Foundations 3.4 Solving Problems Using Acute Triangles Goal: Solve problems using the primary trig. ratios, the sum of angles in a triangle, and the sine and cosine laws. … WebIt helps us solve some triangles. Let's see how to use it. Example: How long is side "c" ... ? We know angle C = 37º, and sides a = 8 and b = 11. The Law of Cosines says: c 2 = a 2 + b 2 − 2ab cos(C) Put in the values we know: c 2 = 8 2 + 11 2 − 2 × 8 × 11 × cos(37º)

WebNov 28, 2024 · To help you visualize this, think of an equilateral triangle with sides of length 5. We know that this is an acute triangle. If you plug in 5 for each number in the Pythagorean Theorem we get 52 + 52 = 52 and 50 > 25. Therefore, if a2 + b2 > c2, then lengths a, b, and c make up an acute triangle. Conversely, if a2 + b2 < c2, then lengths a, b ...
