The cosine of A relates b to the hypotenuse c, so you can first compute c. Once you know b and c, you can find a by the Pythagorean theorem. 33. You know b and cos B. Unfortunately, cos B is the ratio of the two sides you don’t know, namely, a/c. Still, this gives you an equation to work with: 1/3 = a/c. Then c = 3a.For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data. Formula. Description.

Then, write the equation in a standard form, and isolate the variable using algebraic manipulation to solve for the variable. Use inverse trigonometric functions to find the solutions, and check for extraneous solutions. 6cos (30) 6 cos ( 30) The exact value of cos(30) cos ( 30) is √3 2 3 2. 6 √3 2 6 3 2. Cancel the common factor of 2 2. Tap for more steps... 3√3 3 3. The result can be shown in multiple forms. Exact Form: 3√3 3 3.Tan 30 Degrees. The value of tan 30 degrees is 1/√3. The value of tan π/6 can be evaluated with the help of a unit circle, graphically. In trigonometry, the tangent of an angle in a right-angled triangle is equal to the ratio of opposite side and the adjacent side of the angle. Tan 30 degrees is also represented by tan π/6 in terms of radians. .
