WebJul 18, 2024 · Solution: The number of sides of a pentagon (n) = 5. Now, the sum of all 5 interior angles of a pentagon = 180 (n -2)°. = 180 (5 – 2)° = 540°. The sum of the given 4 interior angles = 110°+ 85°+ 136°+ and 105°= 436°. Thus, the fifth interior angle of a pentagon is 104°. WebSolving SSS Triangles. "SSS" means "Side, Side, Side". " SSS " is when we know three sides of the triangle, and want to find the missing angles. To solve an SSS triangle: use The Law of Cosines first to calculate one of the angles. then use The Law of Cosines again to find another angle. and finally use angles of a triangle add to 180° to find ... WebMar 26, 2016 · Solve for the missing side. You divide by sin 68 degrees, so. Repeat Steps 3 and 4 to solve for the other missing side.
