Answer:
[tex]\cos 60= \frac{1}{2}[/tex]
[tex]\tan 60 = \sqrt{3}[/tex]
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, [tex]\cos 60= \frac{Base}{Hypotenuse} = \frac{4}{8} = \frac{1}{2}[/tex]
Again. [tex]\tan 60 = \frac{Perpendicular}{Base} =\frac{4\sqrt{3} }{4} =\sqrt{3}[/tex]
