16 wrz 2022 · When calculating the trigonometric functions of an acute angle A, you may use any right triangle which has A as one of the angles. Since we defined the trigonometric functions in terms of ratios of sides, you can think of the units of measurement for those sides as canceling out in those ratios.
Evaluate trigonometric functions of acute angles. Find unknown side lengths and angle measures of right triangles. Use trigonometric functions to solve real-life problems.
