An acute angle θ is in a right triangle with cos θ = nine tenths. what is the value of sec θ?

Step-by-step explanation:

Trigonometric is made up of two words trigon and metric .

Trigon means triangle and metric means measurement .

Trigonometric ratios basically define the relationship between the angles and sides .

We talk about trigonometric ratios in a right angled triangle .

For any triangle , there are six trigonometric ratios .

We have trigonometric ratios : such that following relations hold :

Given:

To find :

Solution:

We know that , so ,
