Question

Find the value of x.
Right triangle: Hypotenuse is 11, base is x, angle is 22 degrees.

Answer 1

We know that the trigonometric identity that uses the adjacent side and the hypotenuse is cosine. We can set this up as:

`cos(22) = (x)/(11)`

We need to solve for x, so let's isolate it:

`x = 11cos(22) = 10.2`

So, x = 10.2 units
