Final answer:
Solving a triangle involves finding all unknown angles and sides, using laws of sines, cosines, or trigonometric ratios. Angles sum up to 180 degrees, and special symbols represent degrees, minutes, and seconds in angle measurements.
Step-by-step explanation:
When asked to solve the triangle, you are being asked to find all the unknown angles and sides of the triangle. Typically, this would involve applying the law of sines, the law of cosines, or trigonometric ratios if it's a right triangle. To solve for angles or sides, data like side lengths and angle measurements are necessary. The sum of the angles in any triangle is always 180 degrees, so if you know one or two angles, you can calculate the remaining angle. It seems like parts of the question might be missing because there are placeholders (1) ∠a = 2) = 3) =) where the data should be. Nevertheless, when entering data into a calculator or computer to solve for a linear equation, you may need to round answers to four decimal places. For angles measured in degrees, minutes, and seconds (DMS), you use the symbol "°" for degrees. One degree is equal to 60 minutes ('), and one minute is equal to 60 seconds (").
