Answer: [tex]\cos H=\frac{k}{j}[/tex]
Step-by-step explanation:
By trigonometry, In a right triangle, the value of cosine of angle x is given by :-
[tex]\cos x=\frac{\text{Side adjacent to x}}{\text{Hypotenuse}}[/tex]
In the given right triangle, the side opposite to the right angle =j
⇒Hypotenuse = j
The side adjacent to angle H= k
Therefore,
[tex]\cos H=\frac{\text{Side adjacent to H}}{\text{Hypotenuse}}\\\\\Rightarrow\cos H=\frac{k}{j}[/tex]
