WebFeb 14, 2024 · 1 Answer marfre Feb 14, 2024 60∘ Explanation: arccos(1 2) means give me the angle that gives a cos(1 2). If you look at a trig circle in the first quadrant, the angle with a cos( 1 2) is 60∘. This is found in the first quadrant because of the restricted domain and range of the function. WebSo if you use a calculator to solve say arccos 0.55, out of the infinite number of possibilities it would return 56.63°, the one in the range of the function. Things to try. In the figure above, click 'reset' and 'hide details'. Adjust the triangle to a new size Using the arccos function calculate the value of angle C from the side lengths
