How to solve cosine without calculator
WebSep 11, 2024 · On this website i learnt how to find inverse cosine without using calculator with estimating formulated but the problem was it was for only cosine function but I want for sine and tangent as well . Please can anyone introduce or share those estimating formulated . I have been searching these formulated from long time WebThe angle the cable makes with the seabed is 39°. The cable's length is 30 m. And we want to know "d" (the distance down). Start with: sin 39° = opposite/hypotenuse. Include lengths: sin 39° = d/30. Swap sides: d/30 = sin 39°. Use a calculator to find sin 39°: d/30 = 0.6293…. Multiply both sides by 30: d = 0.6293… x 30.

WebSo all we need to do is-- well we can simplify the left-hand side right over here. 65 plus 90 is 155. So angle W plus 155 degrees is equal to 180 degrees. And then we get angle W-- if we subtract 155 from both sides-- angle W is equal to 25 degrees. And we are done solving the right triangle shown below.
