Answer:

\cos 60= \frac{1}{2}

\tan 60 = \sqrt{3}

Step-by-step explanation:

See the diagram given with the question first.

Here we are given a right triangle with two angles other than the right angle are 60° and 30°.

The length of the side opposite to 30° is 4 and the side opposite to 60° is 4√3 and automatically the length of the hypotenuse is 8.

Now, \cos 60= \frac{Base}{Hypotenuse} = \frac{4}{8} = \frac{1}{2}

Again. \tan 60 = \frac{Perpendicular}{Base} =\frac{4\sqrt{3} }{4} =\sqrt{3}
