Right Triangles and SOHCAHTOA: Finding the Length of a Side

: Substitute the known information into the formula: (Note that we dropped the units of “inches” for simplicity.) Step 7: Solve for y. In this example, it is probably simplest to multiply both. sides by 18: Step 8: Simplify. In this case, an approximate value for the sine of 54 degrees is 0.80902. Step 9: ................
