Question

Find the value of cos H rounded to the nearest hundredth, if necessary. 21 F G 2 5 H​

Answer 1

`\huge\boxed{\sf cos \theta = 0.40}`

Explanation:

For angle H:

Hypotenuse = 5

Adjacent = 2

Opposite =
`√(21)`

Solution:

Using trigonometric ratio to solve the question.

We know that,

cos θ = adjacent / hypotenuse

cos θ = 2/5

cos θ = 0.40

`\rule[225]{225}{2}`
