Question

Which trigonometric function would be used to find the length of this triangle's hypotenuse?

Answer 1

B. cosine 25 degrees

because cosine = adjacent / hypotenuse

Answer 2

Answer:

Cos 25° = $\frac{adjecent}{hypontnuse}$.

Step-by-step explanation:

Given : A right angled triangle with angle 25° and side = 12 cm

To find : Which trigonometric function would be used to find the length of this triangle's hypotenuse.

Solution : We have given that adjacent side  = 12 cm ,

By the trigonometric ratio

Cos (theta) = $\frac{adjecent}{hypontnuse}$.

Therefore, Cos 25° = $\frac{adjecent}{hypontnuse}$.

Therefore, Cos 25° = $\frac{adjecent}{hypontnuse}$.
