This document contains calculations to solve for various angles and measurements related to trigonometry. It includes the following steps: (i) Calculates the length of one side of a triangle using trigonometric functions (ii) Sets up an equation involving trigonometric functions to solve for an angle (iii) Solves the equation from part (ii) to find the measure of an angle (iv) Uses trigonometric functions and information from previous calculations to find the measure of another angle (v) Finds the measure of a final angle by relating it to previous results.
