Question

What is the value of cos theta in the diagram below?

Answer 1

The answer is A, 3/5.

Answer 2

The value of cos theta in the diagram below is:

0.6=3/5

Explanation:

We are asked to find the value of cos theta with the help of the given figure.

We know that the cos theta is also defined as a ratio of the base to the hypotenuse of the right triangle that is formed by enclosing that angle theta.

i.e. in the given triangle we have:

The base of the right triangle with respect to angle theta is:AC=0.6 units.

Also, hypotenuse of the right triangle is: AB=1 units.

Hence,the value of cos theta is:

`\cos \theta=(AC)/(AB)\\\\\cos \theta=(0.6)/(1)\\\\\cos \theta=0.6=(3)/(5)`

Hence, the value of cos theta is:

0.6=3/5
