Question

The program should be in C programming

The law of sines is an equation relating the lengths of the sides of an arbitrary triangle to the sines of its angles. Such that if we have the following triangle: sin a sin ß sin y A B C B Write a program that takes the values of angle a, angle B and length of A from a user. These input values are passed to a function find which calculates the angle y and the length of C. Remember that the total sum of all angles in the triangle is 180° (1.e. a + B+ y = 180°). The calculated angle y and the length of C should then be displayed on the screen. Note the following: Ensure that the values for a, ß and C taken from the user are always positive (unsigned) integers. Ensure that the sum of the of values for a, B taken from the user is less than 180° Remember that the sin(), cos() and tan() functions are available in the math.h file Be mindful of your choice of data types 1 1
