To use trigonometric functions to find sides and angles of right triangles.
Learning Goal:To use trigonometric functions to find sides and angles of right triangles.The functions sine, cosine, and tangent are called trigonometric functions (often shortened to "trig functions"). Trigonometric just means "measuring triangles." These functions are called trigonometric because they are used to find the lengths of sides or the measures of angles for right triangles. They can be used, with some effort, to find measures of any triangle, but in this problem we will focus on right triangles. Right triangles...

Write a program to compute the area of a triangle using side-angle-side method and reports the area of that triangle (rounded to 2 decimal places). Side-angle-side formula: ???? = 1/ 2 ?? sin(?), where a and b are two sides of the triangle, and C is the included angle. Your program must meet the following criteria to receive full marks: • Randomly generate two values between 5 and 10 (inclusive) for two sides a and b of the triangle, respectively....
