How to solve a right triangle with 2 sides
WebMultiply both sides by 4.7: sin B = (sin (63°)/5.5) × 4.7 Calculate: sin B = 0.7614... Inverse Sine: B = sin−1 (0.7614...) B = 49.6° Sometimes There Are Two Answers ! There is one very tricky thing we have to look out for: Two possible answers. Imagine we know angle A, … WebTo find the area of a right triangle we only need to know the length of the two legs. We don’t need the hypotenuse at all. That’s because the legs determine the base and the height of the triangle in every right triangle. So we use the general triangle area formula (A = base • height/2) and substitute a and b for base and height.
