Question

What is cosH for this triangle?

Enter your answer in the boxes.

cosH=

Answer 1

Answer:
`\cos H=(k)/(j)`

Explanation:

By trigonometry, In a right triangle, the value of cosine of angle x is given by :-

`\cos x=\frac{\text{Side adjacent to x}}{\text{Hypotenuse}}`

In the given right triangle, the side opposite to the right angle =j

⇒Hypotenuse = j

The side adjacent to angle H= k

Therefore,

`\cos H=\frac{\text{Side adjacent to H}}{\text{Hypotenuse}}\\\\\Rightarrow\cos H=(k)/(j)`

Answer 2

Cos H = k / j.

Explanation:

Cos H = adjacent side / hypotenuse

= k / j.
