Sin Cos Tan 53. These trigonometry values are used to measure the angles and sides of a right angle triangle. Cos sa mi.
3 5 tan 53 4 5 x 5 3 tan 53 4 3. As increases by from increases by. From here solve for x.
Here in this picture you can see the desired triangle.
Quadrants i ii iii and iv they are numbered in a counter clockwise direction in quadrant i both x and y are positive. For a given angle θ each ratio stays the same no matter how big or small the triangle is. Use sohcahtoa and set up a ratio such as sin 16 14 x. Set up the following equation using the pythagorean theorem.
