This rule allows us to relate all three sides and the angle between them. We squared the known side lengths, subtracted the product involving the cosine of the angle, and took the square root of the result. The cosine function helps adjust for the angle\u2019s influence on the length of the opposite side. After careful calculation, we found that the side opposite the 56-degree angle is about 5.5 units long.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-809.jpeg\" alt=\"\" class=\"wp-image-36642\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-809.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-809-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-809-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>&#8216;Find the value of x in the triangle shown below Find the value of &amp; in the triangle shown below: 1 5.7 x 6 6 56&#8217; The Correct Answer and Explanation is: To solve for xxx in the triangle, we must assume the triangle involves sides and angles in a known configuration.
