Apoint on the terminal side of an acute angle in standard position is (1, 2 √2). find the cosine value of this angle. 1/3 1 2√2/3 2√2

Step-by-step explanation:

The point at the terminal side of an acute angle is given by .

That is,

and .

Let r be the length of line segment drawn from the origin to the point and is given by the formula:

Substituting the values of x and y into r,

Thus,

Also, is given by:

Substituting values of x and r,

the answer is 48m^2!
