Finding the area of a triangle trigonometry

WebThe equilateral triangle can be split into two right-angled triangles. The length of the third side of the triangle can be calculated using Pythagoras' theorem. \[c^2 = a^2 + b^2\] \[2^2 = a^2 + 1^2\] WebUse a calculator to find sin 39°: d/30 = 0.6293... Multiply both sides by 30: d = 0.6293… x 30 d = 18.88 to 2 decimal places. The depth "d" is 18.88 m Exercise Try this paper-based exercise where you can calculate the sine function for all angles from 0° to 360°, and then graph the result.
