$\cos{(30^°)} \,=\, \dfrac{\sqrt{3}}{2}$ The value of cos of angle $30$ degrees is equal to $\dfrac{\sqrt{3}}{2}$ in fraction form exactly. It is an irrational number and equals to $0.8660254037\ldots$ in decimal form and the same value is considered as $0.866$ approximately in mathematics. The value of cos $30^°$ is usually called as

If the angle in a right-angled triangle is 30 degrees, then the value of cosine is known as cos of angle 30 degrees. The cosine of angle 30 degrees in the Sexagesimal angle measuring system is written or expressed as cos (30°). cos (30°) = √3/2 In the fraction format, the value of cos (30°) is equal to √3/2.

void x component = OB = -25 Cos 30 deg = -21.7. y component = AB = -25 Sin 30 deg = -12.5 m. Note that each component is pointing along the negative coordinate direction and thus we must take it as negative. Now we will solve a problem using the component method. Question. Find the resultant of the following two displacements: 2 m at 30 deg and 4 m 2019-03-28 Without using calculator,evaluate Sin15 deg,Cos 15 deg,Sin 75deg. O need the answer urgently pls.
