In particular, it will allow us to ...

Finding the length of a side in a right-angled triangle

WebThe steps involved with finding the length of a missing side of a right triangle. WebDec 11, 2024 · Because the angles in the triangle add up to 180 degrees, the unknown angle must be 180° − 15° − 35° = 130°. This angle is opposite the side of length 20, allowing us to set up a Law of Sines relationship. sin(130 ∘) 20 = sin(35 ∘) a asin(130 ∘) = 20sin(35 ∘) a = 20sin(35 ∘) sin(130 ∘) ≈ 14.98. microwave oven price in ethiopia https://1stdivine.com
